技术简介

该技术为醋酸和混合丁烯在固体酸催化剂作用下直接加成生成醋酸仲丁酯，具有低温、低压、正丁烯转化率高的优点。该技术在工程运行过程中能够保持稳定，对环境不敏感。采用本技术的工业装置已在南京百润建成投产，在工艺设计、参数选取等方面具有丰富的知识、经验积累，受干扰程度低。

Introduction

This technology directly adds acetic acid and mixed butene under the action of the solid acid catalyst togenerate sec-butyl acetate. lt has the advantages of low temperature, low pressure and high n-buteneconversion rate. This technology can remain stable and is insensitive to the environment during the projectoperation. The industrial plant adopting this technology has been built up and put into operation by NanjingBairun. lt accumulates rich knowledge and experience in process design, parameter selection and other aspects.and is less susceptible to interference.
