Condensation reaction method for synthesizing meta-position and para-position 2-(tert-butylperoxyisopropyl)benzene

Abstract

The invention discloses a condensation reaction method for synthesizing meta-position and para-position 2-(tert-butylperoxyisopropyl)benzene. The synthesis reaction process comprises the following step: step S1, metering and adding the raw material TBHP (tert-butyl hydroperoxide) with a concentration of 70% into a condensation reaction kettle according to a charging ratio of 2-cumenol m+pDC to TBHP of 1: (2.3-2.8) (mol ratio), and carrying out full stirring. The invention provides the synthesis method for preparing meta-position and para-position 2-(tert-butylperoxyisopropyl)benzene (m+pBIPB for short) through condensation reaction of meta-position and para-position di-(2-hydroxy-2-propyl)benzene (m+pDC for short) and tert-butyl hydroperoxide (TBHP for short), so the use amount of the sulfuric acid with the concentration of 70% can be remarkably reduced, the treatment amount of high-concentration waste acid and sewage can be reduced, sodium hydroxide alkali liquor required for treating waste acid and inorganic salt during wastewater treatment can be reduced, and a novel formula and a novel process for safe production can be ensured.

Description

technical field [0001] The present invention relates to a kind of chemical synthesis method of organic peroxide, uses meta-position+para-position two-(2-hydroxyl-2-propyl) benzene, namely meta-position+para-position 2-cumyl alcohol (abbreviated as m+ pDC), and tert-butyl hydroperoxide (abbreviated TBHP) condensation reaction, obtains the synthetic method of meta-position+para-position 2-(tert-butylperoxyisopropyl)benzene (abbreviated m+pBIPB). Background technique [0002] The production of organic peroxide BIPB usually uses a large amount of 70%-sulfuric acid as a catalyst. After the reaction is completed, a large amount of waste sulfuric acid is produced, causing great environmental pressure. In order to neutralize a large amount of waste sulfuric acid, it is necessary to invest more 30% %NaOH solution is used for acid-base balance, which further causes raw material loss and production waste.

[0002] The production of organic peroxide BIPB usually uses a large amount of 70%-sulfuric acid as a catalyst. After the reaction is completed, a large amount of waste sulfuric acid is produced, causing great environmental pressure. In order to neutralize a large amount of waste sulfuric acid, it is necessary to invest more 30% %NaOH solution for acid-base balance, resulting in raw material loss and production waste

[0003] Or use volatile solvent oil and the water generated by the condensation reaction to azeotrope together for dehydration to achieve the purpose of advancing the reaction, but the boiling point of solvent oil itself is very low and volatile, which can easily cause process safety problems during the reaction process
