Methyl amine (Chem.), a colorless, inflammable, alkaline
gas, CH3.NH2, having an ammoniacal, fishy odor. It is
produced artificially, and also occurs naturally in
herring brine and other fishy products. It is regarded as
ammonia in which a third of its hydrogen is replaced by
methyl, and is a type of the class of substituted
ammonias.
Methyl ether (Chem.), a light, volatile ether CH3.O.CH3,
obtained by the etherification of methyl alcohol; --
called also methyl oxide or dimethyl ether.
Methyl green. (Chem.) See under Green, n.
Methyl orange. (Chem.) See Helianthin.

Methylal
(gcide) | Methylal \Meth"yl*al\, n. [Methylene + alcohol.] (Chem.)
A light, volatile liquid, H2C(OCH3)2, regarded as a complex
