2-ethyl-2-methylhexanoic acid

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: 316 gm (2moles) of 2-methyl-2-ethyl-hexanoic acid were heated to boiling with 357 gm (3 moles) of thionyl chloride under agitation until the evolution of gas had ended. The surplus thionyl chloride was distilled off and the residue was fractionated in vacuo. 320 gm (90% of theory) of 2-methyl-2-ethyl-hexanoyl chloride of b.p. 78° C. at 13 mmHg were obtained. The surplus thionyl chloride was distilled off
