Process model and economic analysis of itaconic acid production from dimethyl succinate and formaldehyde

摘要

A complete process model and economic analysis has been developed for itaconic acid production via catalytic condensation of dimethyl succinate and formaldehyde. The process model is based on experimental yields and selectivities obtained for the condensation reaction and on recovery schemes for itaconic acid developed in our laboratory. For an 18 million kg/yr (40 million lb/yr) itaconic acid production facility with a 10-year lifetime, the model predicts a capital investment of
