Title:
PREPARATION SYSTEM AND PROCESS FOR 1,4-BUTANEDIOL
Document Type and Number:
WIPO Patent Application WO/2021/042579
Kind Code:
A1
Abstract:
The present invention is suitable for use in the technical field of 1,4 -butanediol preparation, and provides a preparation system and process for 1,4-butanediol, comprising a formaldehyde generating apparatus, an acetylene generating apparatus, microinterface generators, a deionising system, and hydrogenation systems; output ends of the formaldehyde generating apparatus and the acetylene generating apparatus are connected to an alkylation reaction apparatus by means of a first microinterface generator; an output end of the deionising system is connected to the hydrogenation systems by means of second microinterface generators; the formaldehyde generating apparatus comprises a heating system, a reaction system, and a product collection system connected to one another, the reaction system comprising a flame retardant filter, a reactor, and an absorption tower; and the heater comprises a first heater and a second heater. Thus, by means of improving the traditional 1,4-butanediol production process, the present invention reduces enterprise equipment upgrade costs and increases reaction efficiency.
