is a gas soluble in water, and a solution of 40 per cent, strength is an article of commerce, largely used for disinfecting and preservative purposes. It has a very irritating action on the mucous membranes of the eyes, nose, and throat. It is made by a contact action brought about by passing a current of methyl alcohol vapour admixed with air over a glowing platinum or copper spiral, and absorption in water, in which solution it has the hydrate formula CH22. It possesses the property of making gelatine in any form insoluble in water, and this is utilized in many technical applications, including the preservation of adhesives and anatomical specimens. It is also used in the processes of making bakelite and other allied articles. The polymeric solid white paraform is more useful for disinfecting rooms by fumigation, as it is easily vaporized and is equally effective per unit of active agent. Formaldehyde is believed to play an important part in the process of plant assimilation.
