In an article, published in an article,once mentioned the application of 37830-90-3,molecular formula is , is a conventional compound. this article was the specific content is as follows. 37830-90-3
REFERENCE EXAMPLE 2 Preparation of 4-chloromethyl-5-methyl-1,3-dioxolene-2-one (II) To a solution of 75 g of 4,5-dimethyl-1,3-dioxolene-2-one (IV) in 750 ml of methylene chloride was added 97.6 g of sulfuryl chloride dropwise at 40¡ã-42¡ã C. over 2 hours. The mixture was stirred for 40 minutes at the same temperature and evaporated in vacuo to remove the solvent. NMR spectrometry of the resulting oil revealed that the product was 4-chloro-4-methyl-5-methylene-1,3-dioxolane-2-one (III) containing a trace amount of unreacted 4,5-dimethyl-1,3-dioxolene-2-one (IV). This oil was heated at 90¡ã C. with stirring for 2 hours without isolating 4-chloro-4-methyl-5-methylene-1,3-dioxolane-2-one (III) and then distilled in vacuo. 75.4 g (corresponding to an overall yield from 4,5-dimethyl-1,3-dioxolene-2-one (IV) of 77percent) of 4-chloromethyl-5-methyl-1,3-dioxolene-2-one (II) having the physicochemical properties described in Reference Example 1 was obtained.
The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 37830-90-3 is helpful to your research. 37830-90-3
