2,2-Dimethoxypropane Chemical Properties,Usage,Production
Chemical Properties
colourless liquid; B.P. 83℃. Ethereal odor. Soluble in alcohol, miscible with ess, oils and perfume chemicals. Stable when pure and at room temp. Decomposes into Acetone and Methanol during heating in presence of moisture or traces of mineral acid. Presumably not used in flavors. Rarely used in perfumes - for ethereal top-notes and "alcohol-like" effects. Produced synthetically via orthoformic ester or vinyl ether. Also from formiminomethyl-ether hydrochloride.
Uses
2,2-Dimethoxypropane acts as a dehydrating agent. It also serves as an intermediate in the synthesis of vitamin E, vitamin A and various carotenoids such as astaxanthin. It is used as a reagent for the preparation of 1,2-diols, acetonides, isopropylidene derivatives of sugars, nucleosides, methyl esters of amino acids and enol ethers.
Uses
2,2-Dimethoxypropane(DMP) is used in histology and considered to be more efficient than ethanol for the dehydration of animal tissue.
General Description
2,2-Dimethoxypropane is an organic compound, which may be used as a protecting agent in the process of the synthesis of structurally related alkaloids like narciclasine and lycoricidine using phenylbromide as the starting material.
Toxics Screening Level
The ITSL for 2,2-Dimethoxypropane is being set at the default value of 0.1 μg/m3 with annual averaging under 232(1)(i).
