Process for synthesizing1,3,5-triphenyl benzene

Abstract

The invention discloses a 1, 3, 5-triphenyl benzene synthesizing method, which comprises the following steps: dissolving acetophenone in n-amyl alcohol; mixing and adding in accelerant tin tetrachloride; putting in accelerant p-toluenesulfonic acid; reacting at 110deg.c for hours; pouring out reactant in absolute ethyl alcohol; mixing; filtering; using carrene-alcohol for recrystallization; getting 1,3,5-diphenylbenzene benzene. The invention solves the problem of the carbonization of corrosive acid catalystsing and synthesizing 1, 3, 5-triphenyl benzene, which reduces the reaction yield and environmental contamination.

Description

technical field

[0001] The present invention relates to 1,3,5-triphenylbenzene, in particular to a synthesis method of 1,3,5-triphenylbenzene. Background technique

[0002] 1,3,5-Triphenylbenzene is a class of aromatic compounds with a special structure. It is an important basic functional module for the construction of dendrimers, organic conductive polymers and polarized nonlinear optical materials. It is also a class of promising electroluminescent organic molecular materials.

[0003] Prior to the present invention, the synthesis method of 1,3,5-triphenylbenzene included the use of rare earth chlorides, strong acids, silicon tetrachloride and aluminum trichloride to catalyze the synthesis of acetophenone trimolecular condensation. However, most of these reactions have defects such as cumbersome operation, harsh reaction conditions, or long reaction time. The specific performance is as follows:
