This product offers a purity level of ≥99.5%, ensuring chemical stability critical to sensitive applications. It exhibits moderate evaporation rates and neutral acidity, making it suitable for complex synthesis environments without introducing unwanted acidity effects. The colorless, transparent liquid form with mild aromatic odor supports visual quality control during handling. Produced using controlled manufacturing processes, it possesses low moisture content and consistent physicochemical parameters such as vapor pressure and viscosity, which facilitate reliable dosing and process predictability.
The n-Butanol product is extensively applied as an alcohol solvent in coatings, inks, and plasticizer synthesis — notably in phthalate ester production. It functions as an extraction agent in pharmaceuticals, oils, and fragrances, reinforcing its versatility as a liquid chemical in various industrial sectors. By offering stable batch composition, it supports industrial chemicals suppliers and manufacturers in reducing variability during formulation and enhancing product quality consistency, thereby improving process yield and compliance with industrial standards.
The design and production system of this n-Butanol ensures low impurity levels and moisture content, supporting seamless integration into chemical manufacturing processes managed by industrial chemicals suppliers. Its packaging and quality control systems are engineered to maintain chemical integrity during storage and transit, which is crucial for maintaining the purity essential for advanced organic alcohol applications. The product’s consistency in key physical properties facilitates modular incorporation into solvent blends or raw material inputs across diverse chemical synthesis platforms.
With high purity and moderate volatility, this alcohol solvent performs effectively across varied chemical reactions and formulation tasks, minimizing unpredictable interactions or degradations. The consistent physicochemical profile enhances operational reliability and reduces monitoring complexity for chemical manufacturing facilities. Users benefit from reduced downtime and streamlined process control while handling a liquid chemical that aligns with industrial requirements for reproducibility and material compliance.

n-Butanol — sold as 1-butanol, butyl alcohol or propylcarbinol — is a four-carbon straight-chain primary alcohol with the formula C₄H₁₀O. We manufacture it in Shandong at ≥99.5% purity, with moisture and impurity levels held low enough that a reactor or a let-down tank receives essentially the same material from lot to lot.
Its position in the alcohol range is what makes it so widely used. Evaporation sits in the middle: slower than methanol or the acetates, the fast-release solvents that methanol solvent suppliers commonly offer, and faster than the glycol ethers, which leaves a film enough time to flow out and level before it sets. Solvency is broad enough to carry alkyd and urea-formaldehyde resins in solution, and the straight C4 chain esterifies predictably in a reactor, which is why plasticizer production is its largest single outlet.
Three groups buy it from us. Plasticizer producers esterify it into dibutyl phthalate and related esters for PVC compounds; coatings and ink manufacturers use it to hold resin in solution and to tune viscosity and drying; industrial cleaners blenders use it as a coupling solvent that keeps water and solvent in one phase. Extraction of oils, flavours, antibiotics, hormones and vitamins is the fourth, quieter outlet. We are one of the alcohol producers and a methanol solvent manufacturer working out of the Dongying petrochemical base, so a plant running several solvent lines can qualify a single source instead of four.

Coatings
Alkyd air-drying enamels and stoving systems built on urea-formaldehyde or melamine resins are the two places n-Butanol is used most. In an alkyd it behaves as a latent solvent: it holds the resin in solution through the early part of the dry and releases as the film builds, so the coating levels instead of setting with brush marks. In an amino resin baking system it improves compatibility across the solvent package and helps the film flow before the oven.
Inks
In ink the job is viscosity and set speed. The alcohol thins the ink without collapsing its structure and gives the press a working window wide enough for a long run. Formulators often pair it with a faster methanol solvent from their existing methanol solvent suppliers: the fast component carries the initial release, the butanol keeps the resin in solution and the film open, and the two together dry more evenly than either does alone.
Industrial cleaners
Because n-Butanol is only partly soluble in water, it works as a coupling solvent in cleaner concentrates — it holds solvent and water in a single stable phase, keeps surfactants from separating out, and lifts oily soil without the film a pure hydrocarbon leaves behind. Its moderate evaporation also keeps the cleaner wet on the surface long enough to work.
What to watch
Any change of alcohol changes open time. If you are moving a fast-drying system onto n-Butanol, run a bench batch and compare the drying curve and film appearance against your current standard before the change goes to the line.

Shandong Yingtai Chemical Co., Ltd. operates from Dongying, Shandong, in the heart of China's petrochemical industry and home to the Shengli Oilfield. Our 60,000㎡ park-based facility runs modern plants with automated control systems and integrated utilities, and a team of over 200 people covers R&D, production and sales of high-value-added fine chemicals. We supply seven core chemical categories, backed by stable quality and consistent availability, and work alongside buyers on sourcing, product application and technical support. Custom requirements are reviewed case by case — share your specification and volume and we will confirm feasibility.
Yes — n-Butanol, 1-butanol, butyl alcohol and propylcarbinol all describe the same straight-chain C4 alcohol. The prefix marks the normal, unbranched structure, which is what separates it from isobutanol, a branched isomer with different solvency and evaporation behaviour. If your specification was written around 1-butanol, this is the same material.
It narrows the variables. With moisture and impurities held low and the acidity neutral, the alcohol contributes less water to an esterification, produces less colour in the finished ester, and behaves the same way from lot to lot — so a coating or plasticizer recipe that is dialled in stays dialled in. Less of the alcohol is also consumed by side reactions.
Yes. Its partial water solubility makes it a useful coupling solvent in industrial cleaners, where it holds solvent and water in one phase and keeps surfactants in solution. It also evaporates slowly enough to leave the cleaner working on the surface rather than flashing away. Test the ratio in your own blend against your current standard before you commit a production batch.
Not as a straight swap. Methanol is a single-carbon alcohol that evaporates much faster and mixes with water in any proportion; n-Butanol has a slower release and only slight water solubility, but far better solvency for alkyd and urea-formaldehyde resins. Moving from methanol to n-Butanol changes drying time, film flow and water tolerance together, so treat it as a reformulation and run a bench batch first.
Yes. n-Butanol ships alongside our other fine chemicals, and we are among the methanol manufacturers serving buyers from the Dongying base, so a plant can source several alcohols from one supplier. Wholesale methanol can be planned on the same schedule as butanol. If a separate production line needs a wholesale methanol solvent, raise it in the same enquiry and we will align the two.
With one specification and one loading plan. Whether you approach us as one of the region's methanol manufacturers or for butanol alone, the approval and inspection routine stays the same, so your team is not re-approving a new supplier for every line. The same sales contact can coordinate both products, keeping scheduling and paperwork to a single thread.
