Description

n-Butyl alcohol is a colorless flammable liquid with a strong alcoholic odor. n-Butyl alcohol is a highly refractive liquid and burns with a strongly luminous flame. It is incompatible with strong acids, strong oxidizing agents, aluminium, acid chlorides, acid anhydrides, copper, and copper alloys. n-Butyl alcohol has extensive use in a large number of industries. For instance, it is used as a solvent in industries associated with the manufacturing of paints, varnishes, synthetic resins, gums,

Usage

As a chromatographic analysis reagent, it is also used in organic synthesis, etc.; butanol is a food flavor permitted in my country's "Sanitary Standards for the Use of Food Additives", and is mainly used to prepare banana, cream, whiskey and cheese flavors. The amount used in candy is 34mg/kg; baked food is 32mg/kg; soft drinks are 12mg/kg; cold drinks are 7.0mg/kg; cream is 4.0mg/kg; alcohol is 1.0mg/kg. Butanol is an intermediate of the herbicides 2,4-D butyl ester, butachlor, diflufen-op-p-ethyl (Penoxazone) and fine diflufen-op-ethyl. GB2760—96 stipulates that it is allowed to use edible spices. Mainly used to prepare flavors such as banana, cream, whiskey and cheese. Also used as extraction solvent and pigment diluent. It is mainly used in the manufacture of n-butyl ester plasticizers of phthalic acid, aliphatic dibasic acid and phosphoric acid. They are widely used in various plastics and rubber products. It is also a raw material for the production of butyraldehyde, butyric acid, butylamine and butyl lactate in organic synthesis. It is also an extractant for oils, drugs (such as antibiotics, hormones and vitamins) and spices, and an additive for alkyd resin coatings. It can also be used as a solvent and dewaxing agent for organic dyes and printing inks. Used in the production of butyl acetate, dibutyl phthalate and phosphoric acid plasticizers, and also used in the production of melamine resin, acrylic, epoxy varnish, etc.

Production Methods

Fermentation method uses corn starch (wheat, corn, etc.) starch as raw material, add water to prepare mash, inoculate acetone butanol bacteria after cooking and sterilize, and ferment at 36~37℃. The fermentation mash is separated by distillation to obtain butanol, acetone and ethanol, butanol accounts for 55% to 58%, acetone accounts for 30Z to 34%, and ethanol accounts for 7% to 14%. Molasses or potato starch can also be used as raw materials. The carbonyl synthesis method, or REPPE method, uses propylene, carbon monoxide and water as raw materials to directly synthesize butanol in one step. When the reaction temperature is 100~104℃ and the pressure is 1.47MPa, the anionic complex formed by n-butylpyrrolidine, iron pentacarbonyl and water is used as the catalyst component, butanol is used as the solvent, and the conversion rate is 8%~ 10%, the yield of n-butanol is 87%. The raw materials of this method are easily available and the process is simple, but the conversion rate in one pass is not high, which requires high concentration of carbon monoxide in the raw materials. In aldol condensation method, acetaldehyde is first added to 10% dilute alkaline solution, and the reaction is performed below 120°C for 0.5 to 2 hours to generate 2-hydroxybutyraldehyde. When the reaction reaches 50%, the alkali is neutralized, and unreacted acetaldehyde is recovered by distillation, and 2-hydroxybutyraldehyde is obtained from the bottom of the distillation tower. It is then dehydrated with sulfuric acid or acetic acid to obtain crotonaldehyde. Using nickel chromium as the catalyst, under the conditions of 180°C and 0.29MPa, the crotonaldehyde is hydrogenated and reduced to butanol, and the reaction mixture is fractionated to obtain the product. This method has a long process route and serious equipment corrosion, and currently only a few manufacturers use it.
