paraldehyde's Usage Examples:

When taken continuously the drug soon loses its power as a hypnotic. Its unpleasant taste usually prevents the formation of a paraldehyde habit, but it occasionally occurs with symptoms resembling delirium tremens.

Paraldehyde is a powerful hypnotic, giving a refreshing quiet sleep which is not followed by unpleasant after effects.

in that mixture which contains 88% of paraldehyde and 12% of acetaldehyde, which the catalytic agent leaves unaffected.

The phenomena were first observed without mutual transformation, aldehyde melting at - 118°, paraldehyde at 13°, the only mutual influence being a lowering of melting-point, with a minimum at - 120° in the eutectic point.

The substance investigated was acetaldehyde, C 2 H 4 O, in its relation to paraldehyde, a polymeric modification.

Crotonic acid, so named from the fact that it was erroneously supposed to be a saponification product of croton oil, may be prepared by the oxidation of croton-aldehyde, CH3 CH:CH CHO, obtained by dehydrating aldol, or by treating acetylene successively with sulphuric acid and water; by boiling allyl cyanide with caustic potash; by the distillation of 0-oxybutyric acid; by heating paraldehyde with malonic acid and acetic acid to, oo C. (T.

Paraldehyde is oxidized by dilute nitric acid, with formation of much glyoxal, (CHO) 2.

Paraldehyde is moderately soluble in water, and when distilled with sulphuric acid is reconverted into the ordinary form.

It is readily polymerized, small quantities of hydrochloric acid, zinc chloride, carbonyl chloride, 'c. converting it, at ordinary temperatures, into paraldehyde, (C 2 H 4 0) 3, a liquid boiling at 124° C. and of specific gravity o�998 (15° C.).
