Procedure

The procedures were again followed with substitution in the neutralization step of a number of other carboxylic acids the use of which is not in accordance with the invention. The use of acetic acid resulted in an apparently homogeneous semi-solid or gelatinous product. Butyric acid and hexanoic acid were responsible for production of a two phase mixture containing roughly equal quantities of a lower gel phase and an upper liquid phase. Formic acid, oxalic acid, and carbonic acid each resulted in formation of a white precipitate.

Workup

  1. additioncontaining roughly equal quantities of a lower gel phase
