Methyl acrylate can be prepared by debromination of methyl 2,3-dibromopropanoate with zinc. [10] Methyl acrylate is formed in good yield on pyrolysis of methyl lactate in the presence of ethenone (ketene). [11] Methyl lactate is a renewable "green chemical". Another patent [12] describes the dehydration of methyl lactate over zeolites.
The check digit is found by taking the last digit times 1, the preceding digit times 2, the preceding digit times 3 etc., adding all these up and computing the sum modulo 10. For example, the CAS number of water is 7732-18-5: the checksum 5 is calculated as (8×1 + 1×2 + 2×3 + 3×4 + 7×5 + 7×6) = 105; 105 mod 10 = 5.
Different CAS Registry Numbers [1] are used for each form of a substance. For example, something simple like alanine will have one CAS# for the D form, another for L, another for "unspecified" and a fourth one for racemic. There would be another four CAS#s for the hydrochloride, four for the (1:1) sulfate, four for the (2:1)sulfate, etc.
This alkylation provides a means to separate 2,4-xylenol from 2,5-xylenol since 2,4-dimethyl-6-tert-butylphenol is insoluble in 10% NaOH but 2,5-dimethyl-6-tert-butylphenol is soluble. Subsequent to separation, the tert-butyl group can be removed in strong acid. [1]
Tetramethyl acetyloctahydronaphthalenes (International Nomenclature for Cosmetic Ingredients name) (1-(1,2,3,4,5,6,7,8-ottaidro-2,3,8,8,-tetrametil-2-naftil)etan-1-one) is a synthetic ketone fragrance also known as OTNE (octahydrotetramethyl acetophenone) and by other commercial trade names such as: Iso E Super, Iso Gamma Super, Anthamber, Amber Fleur, Boisvelone, Iso Ambois, Amberlan, Iso ...
Diisobutylamine is an organic compound with the formula ((CH 3) 2 CHCH 2) 2 NH. Classified as a secondary amine , the molecule contains two isobutyl groups. This colorless liquid is a weak base that is useful as an inhibitor of bacterial growth, as a precursor to various fertilizers, and a corrosion inhibitor.
