Synthetic technology of hydroxyethylaniline ester (III)

The invention discloses a synthetic technology of hydroxyethylaniline ester (III). The synthesis process is shown by a chemical equation shown in the description. The technology has the following advantages: 1, the advantage of few instant reaction substances of a micro-channel reactor is used, so the flammable and explosive disadvantages of a hydroxyethylation reaction in a routine kettle are solved, the process safety is increased, and current chemical engineering safety operation requirements are met; and 2, the advantage of high mixing efficiency of the micro-channel reactor is used, the reaction can be carried out under solvent-free conditions when a hydroxyethylation reaction raw material is liquid, and when the excess amount of ethylene oxide is very small, so a reaction solution obtained after the hydroxyethylation reaction ends can be esterified in the micro-channel reactor, serial operation of two-step reactions is realized, and manpower and three wastes are greatly reduced. The technology is a new technology with simplified processes, and accords with environmental protection and safety requirements.
