Hydrochloric Acid → HCID 9841649, compound

Participants

Reaction Steps

A solution of 82 g of glyoxylic acid . 1/2 H2O (1 mol) and 375 g of o-tert.-butyl-phenol (2.5 mols) in 300 ml of benzene was saturated at 40° C wtih gaseous hydrogen chloride and condensed at this temperature. From time to time, saturation was completed by adding a small amount of gaseous hydrogen chloride. After about 40 hours, condensation was complete. The precipitate which had separated upon cooling was suction-filtered and recrystallized from methylene chloride. The yield was 190 g (52 %, calculated on glyoxylic acid), m.p. 173° C.
