Marked Stability

Macrocrystalline cyclic oxalates (2,3-dimethyl-5-6-p-dioxanediones) were prepared by vacuum distillation of the polymeric mixture formed on heating ethyl oxalate, and 1, 2-dimethylethylene glycol with an ester-interchange catalyst. Monomeric dimethylethylene oxalate polymerizes less readily than propylene oxalate, and only at an elevated temperature in the presence of a catalyst. Dimethyl substitution therefore confers marked stability on the six-membered ring. Hydrolysis reaches 50% completion almost instantaneously, followed by a slow first order reaction resulting in complete cleavage of the monobasic acid in about one month at room temperature. Hydrolysis constants for the levo- and meso- oxalates are 0.069 and 0.076 days−1 respectively. The crystalline monomers do not possess sharp melting points and represent stereoisomeric mixtures which display optical activity in solution.

Hydroxypropionic Acid

Those who are conversant with the history of the development of our present theory of structure are aware that the constitution of lactic acid was the subject of discussion, in the years 1858-1860, by the distinguished German chemist Kolbe and the equally distinguished French chemist Wurtz, the latter contending that the acid was diabasic, whilst Kolbe held that it was a monatomic monobasic acid, viz. Hydroxypropionic acid—a view which has long been accepted. The discussion has an important place in chemical literature, as it practically involved the recognition of the doctrine that organic acids owe their distinctive properties to the presence of the carboxyl radicle, (CO. OH).
