1,2,3,4-Tetramethylbenzene Chemical Properties,Uses,Production

Description

1, 2, 3, 4-Tetramethylbenzene is used as a starting material in the preparation of 1, 2, 3, 4-tetramethyl benzene-5-chlorosulfonyl chloride by reacting with chlorosulfonic acid1. In industry, it is the precursor to pyromellitic dianhydride, which is used for manufacturing curing agents, adhesives, coating materials. It is used in the manufacture of some raw materials for engineering plastics (polyimides) and cross-linking agent for alkyd resins. It is also a suitable starting material for the synthesis of hexamethylbenzene2-4.

Chemical Properties

Colorless liquid. Soluble in alcohol; insoluble in water.

Uses

1,2,3,4-Tetramethylbenzene is a useful starting material and building block for organic synthesis. An analyte identified in the volatile oils from Taxodium ascendens leaves and cones. Antibacterial activity.

Definition

ChEBI: A tetramethylbenzene that consists of benzene substituted by methyl groups at positions 1, 2, 3 and 4.

Purification Methods

Dry it over sodium and distil under reduced pressure. The picrate has m 92-95o (EtOH). [Beilstein 5 H 430, 5 I 206. 5 II 329, 5 III 974, 5 IV 1072.]
