Product description:By butyl alcohol and propionic acid reaction. Propionic acid and butanol and heating reflux with 5 h, sulfate with sodium carbonate neutralization after cold to pH7-8, points to the water layer, using anhydrous potassium carbonate and dry, filtering fractionation collecting 145-147 ℃ for finished products. Refined methods: often contain impurities such as free propionic acid and butyl alcohol. After neutralization with sodium carbonate solution, washing water, calcium chloride solution, anhydrous potassium carbonate dry distillation.1. Used for cellulose nitrate, natural and synthetic resins of solvent and paint solvent. Is also used to apricot, peach fruit essence of manufacturing. 2. Used as a solvent, essence, spice nitro cellulose.
