Description
2-METHYL-2-PROPENE-1,1-DIOL DIACETATE is a liquid chemical intermediate with a density of 1.04 g/cm3. It is highly toxic and has chemical properties that make it slightly soluble in water and combustible. 2-METHYL-2-PROPENE-1,1-DIOL DIACETATE is primarily used for its ability to provide controlled release of methacrolein in acid solutions.
Uses
Used in Chemical Industry:
2-METHYL-2-PROPENE-1,1-DIOL DIACETATE is used as a chemical intermediate for the controlled release of methacrolein in acid solutions. This application is particularly important in the production of various chemicals and materials that require a slow and steady release of methacrolein for optimal reaction conditions and product quality.
Used in Pharmaceutical Industry:
Although not explicitly mentioned in the provided materials, due to its controlled release properties, 2-METHYL-2-PROPENE-1,1-DIOL DIACETATE could potentially be used in the pharmaceutical industry for the development of drug delivery systems. Its ability to control the release of active ingredients could be beneficial in designing medications with improved efficacy and reduced side effects.
Reactivity Profile
2-METHYL-2-PROPENE-1,1-DIOL DIACETATE reacts exothermically with acids. Strong oxidizing acids may cause a reaction that is sufficiently exothermic to ignite the reaction products. Heat is also generated with basic solutions. Flammable hydrogen may be generated by mixing with alkali metals and hydrides. Reacts readily with mercaptans. Acidic conditions favor breakdown to methacrolein, which is subject to possibly vigorous polymerization.
Fire Hazard
When heated to decomposition, 2-METHYL-2-PROPENE-1,1-DIOL DIACETATE emits acrid smoke and irritating fumes.
Safety Profile
Poison by inhalation, skin contactand intraperitoneal routes. Moderately toxic by ingestion. When heated to decomposition it emitsacrid smoke and irritating fumes.
Check Digit Verification of cas no
The CAS Registry Mumber 10476-95-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,0,4,7 and 6 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 10476-95:
(7*1)+(6*0)+(5*4)+(4*7)+(3*6)+(2*9)+(1*5)=96
96 % 10 = 6
So 10476-95-6 is a valid CAS Registry Number.

Method for preparing anethol propionaldehyde by anisole
-
Paragraph 0050-0052; 0055-0057, (2021/10/27)
The invention relates to the technical field of organic synthesis, in particular to a method for preparing anethoxyl propionaldehyde by anisole, which comprises anisole and 2 - methylallyl diacetate or anisole. 2 - Methacrolein and acetic anhydride were added to the reaction vessel to catalyze the reaction. Then 1 - acetoxy -2 - methyl -3 - (4 - methoxyphenyl) propylene was added to a reaction vessel carrying an alcoholic solvent and an ester exchange catalyst to carry out an ester exchange reaction. The method solves the problems that the cost of anisic aldehyde or anisaldehyde in the product is high due to the expensive price of anisaldehyde or anethol in the prior art, and anisole is synthesized into anethol propionaldehyde. The synthetic anisanylpropanal has a sufficiently high purity. Can be used for perfumery.

Page/Page column 13-14, (2009/12/05)
Disclosed are: (1) a method for producing 2-methyl-3-(3,4-methylenedioxyphenyl)propanal, which comprises the step of providing a reaction mixture containing 1-acetoxy-2-methyl-3-(3,4-methylenedioxyphenyl)-1-propene by a process for reacting 1,2-methylenedioxybenzene with 2-methyl-3,3-diacetoxypropene or a process for reacting 1,2-methylenedioxybenzene, methacrolein and acetic anhydride with one another; subjecting the reaction mixture to hydrolysis or transesterification with an alcohol to provide a reaction mixture containing 2-methyl-3-(3,4-methylenedioxyphenyl)propanal; and purifying by distilling the reaction mixture, wherein a high boiling point compound contained in the reaction mixture is removed by a specific procedure; and (2) 2-methyl-3-(3,4-methylenedioxyphenyl)-propanal produced by the method, which has an acetic acid content of a less than 40 ppm, is useful as a perfume, and has a high purity.
