Soc. 18 9 3, 63, p. 469); and by passing hydrochloric acid gas into a mixture of aromatic aldehydes and their cyanhydrins (E.
Tetrahydro-oxazoles or oxazolidines result from the action of aldehydes on amino-alcohols (L.
The esters of the acid condense readily with aromatic aldehydes and ketones to form y-disubstituted itaconic acids and y-alkylen pyrotartaric acids (H.
Y-Oxyacids are formed when aldehydes are heated with sodium succinate and sodium acetate.
Villiger (Be y ., 1901, 34, pp. 2679, 3612) showed that many organic compounds (ethers, alcohols, aldehydes, ketones, &c.) behave towards acids, particularly the more complex acids, very much like bases and yield crystallized salts in which quadrivalent oxygen must be assumed as the basic element.
