CLEAR COLOURLESS TO VERY SLIGHTLY YELLOW LIQUID

4-tert-Butylbenzoyl chloride is used as a reactant in the preparation of multi-branched structures based on triphenylamine for enhanced two-photon absorption.

Distil it in a vacuum. If IR shows OH group, then treat it with thionyl chloride or oxalyl chloride at ca 50o for 30minutes, evaporate and fractionate it in a vacuum using a short column. Strongly LACHRYMATORY; use a good fume hood. [Fuson & Turnbull J Am Chem Soc 71 2544 1949, Tsuno et al. Bull Chem Soc Jpn 32 960 1959, Swain et al. J Am Chem Soc 72 5433 1950, Beilstein 9 III 2526.]
