摘　　要：依据清洁生产和绿色化学的基本理念,研究和开发了几种酯类和缩醛缩酮类香料的生产技术,成功合成了中低级脂肪醇的乙酸酯、苹果酯、星苹酯等日化香料产品,并在小试验结果基础上完成了100 L规模的苹果酯合成中间试验和试生产,所有产物中酯的含量一般都在95%以上,稍加精馏提纯即可达到纯度98%以上,实现了工艺过程简单化,催化剂易于回收和再生,基本上没有或仅有很少量的“三废”排放等目标。A method was studied and developed to synthesize esters perfumes according to the principle and conception of green chemistry and clean process. Some esters perfumes such as low- and middle-carbon akyl acetate, fructone-A and fructone-B, etc. were prepared of the method, of which contents of main products were more than 95 %, and purities of the products were more than 98 % after distillation or fine distillation. A pilot test production for synthesizing fructone-A on the scale of 100 L was done according to the experimental results. There are some merits of the method, such as process is simple; catalyst is easy to reuse; and there is very little waste gas, residue, and liquid to be drained.
