Abstract

The invention relates to a compound production method, particularly to a synthesis method and apparatus of hexahydric cyclocompounds by using a continuation method. Dienophile and diene mixtures are added in a multi-segment tubular reactor according to a mol ratio of 1-2:1 to perfrom reaction, the reaction temperature of a first segment is controlled in 50-200 DEG C, the cycle ratio is circulation:discharge=15:1, the discharged portion enters into a second segment of reactor, the temperature is controlled in 100-300 DEG C to perform reaction, the cycle ratio is 5:1, the discharged portion enters into a third segment of reactor, the temperature is controlled in 150-350 DEG C to perform reaction, the discharged material of the end reactor is separated, cooled and then materials are educed to be rectified so as to obtain products, the non-reacted materials is cycled to continue reaction. The invention improves the reaction conversion rate and safty performance, largely reduces energy consumption, enhaces product quality and yield, ensures subsequent product quality.

Description

technical field

[0001] The invention relates to a production method of a compound, in particular to a method for continuously synthesizing a six-membered cyclic compound and a device thereof. Background technique

[0002] Compounds containing a reactive double or triple bond (dienophiles) undergo 1,4-addition to conjugated dienes (dienes) to form six-membered cyclic compounds:

[0003]

[0004] This reaction is named Diels-Alder reaction, which is very easy to carry out and has a fast reaction speed, and has a wide range of applications. It is a very important method for synthesizing cyclic compounds. The Diels-Alder reaction is an unsaturated compound containing a double bond or a triple bond (with carbonyl or carboxyl electron-withdrawing groups on its flanks - a dienophile) and a chain or cyclic compound containing a conjugated double bond system (a diene ) from a "1,4-" addition cyclization reaction to generate a six-membered carbocyclic hydrogenated aromatic compoun...
