Methyl acrylate is manufactured via a reaction of nickel carbonyl and acetylene with methanol in the presence of an acid; more commonly, however, it is manufactured via oxidation of propylene to acrolein and then to acrylic acid. The acid is reacted with methanol to yield the ester. ...
Structure Search About UsMETHYL-D3-ACETYLENE 13025-73-5METHYL-D3-ACETYLENE (CAS 13025-73-5, C3H4), is a colorless gas, widely used in organic synthesis and as a reagent in chemical reactions, with the special property of being a deuterated form of methylacetylene. It plays a crucial role...

The antisymmetric silyl stretching fundamental vibration of methyl(silyl)acetylene gives rise to a perpendicular band in the infrared spectrum of the gas that shows, under a resolution of 0.06 cm 1 , structure associated with internal rotation in the absence of any appreciable barrier to such ...
The hydrogenation of methylacetylene. II. The reaction of methylacetyl... The reaction between methylacetylene and hydrogen over unsupported nickel, iron, and cobalt catalyst has been investigated in a static constant volume system for a wide range of temperature and reactant ratios. The reaction ...
Also found in:Encyclopedia,Wikipedia. (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 rep...
Samples of methyl acetylene with 13C isotopic substitution at all three C positions have been prepared and their IR spectra studied. The resulting vibration frequencies yield accurate frequency shift data, which are of great value in increasing the precision with which the harmonic potential function ...
