Sec-butyl acetate has a variety of uses, mainly used as a solvent. In the past, sec-butyl acetate is got by acetic acid and sec-butanol reaction synthesis, but cost is high, gradually replaced by other products with similar performance. The direct synthesis of sec-butyl acetate by the reaction of n-butene with acetic acid can significantly reduce the production cost.  Olefin synthesis of sec-butyl acetate is in the acidic catalyst under the action of anhydrous acetic acid and n-butene addition reaction and direct synthesis. The catalyst used for the synthesis may include a solid acid catalyst and a liquid acid catalyst, the former comprising a cation exchange resin, solid phosphomolybdic acid, and the latter comprising sulfuric acid and p-toluenesulfonic acid. Former Soviet scientists have also studied the reaction of n-butene with acetate, they used an excess of olefins. Because petroleum pyrolysis gas contains a large amount of unsaturated hydrocarbons, the esterified produc...

We have a professional  Methyl Acetate Plant , where we can provide  Methyl Acetate Production . The following is a brief introduction to the preparation process. Acetic acid and methanol were synthesized with sulfuric acid as catalyst to produce methyl acetate crude products, and then dehydrated with calcium chloride, neutralization of sodium carbonate and the finished product. Refining method: the main impurities are free acetic acid and methanol because of easy hydrolysis of methyl acetate. The existence of methanol can be seen from its solubility in water. At room temperature, methyl acetate dissolved in water by 24%. If 1% methanol exists, it can be mixed with water. When refined, 85mL acetic anhydride was added in 1000mL of methyl acetate, and then fractionated after 6 hours. Acid impurities can be vibrated with anhydrous potassium carbonate and then distilled. The methanol can also be removed by acetyl chlorination. High purity methyl acetate can be washed with sal...
