598-98-1 Usage

Description

Methyl trimethylacetate is a colorless liquid, the methyl ester of pivalic acid. The ester is well known for being resistant to hydrolysis to the parent acid. Hydrolysis can be effected with a solution of trimethylsilyl iodide in hot acetonitrile followed by aqueous workup. It is used to make vinyl chloride resins, as a chemical intermediate, and in adhesives, lubricants, greases, and fuel additives.

Chemical Properties

CLEAR COLOURLESS LIQUID

Uses

Methyl Pivalate is a useful chemical reagent for the preparation of esters and transesterification.

Check Digit Verification of cas no

The CAS Registry Mumber 598-98-1 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,9 and 8 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 598-98:
(5*5)+(4*9)+(3*8)+(2*9)+(1*8)=111
111 % 10 = 1
So 598-98-1 is a valid CAS Registry Number.

A methodical selection process for the development of ketones and esters as bio-based replacements for traditional hydrocarbon solvents

Byrne, Fergal P.,Forier, Bart,Bossaert, Greet,Hoebers, Charly,Farmer, Thomas J.,Hunt, Andrew J.

, p. 4003 - 4011 (2018)

A "top down" approach to the development of sustainable, greener, low-polarity solvents is presented. Methyl butyrate, ethyl isobutyrate, methyl pivalate and pinacolone were identified as potential target solvents from trends in Hansen solubility parameters and known physical properties. Solubility, flammability and physical properties were determined which showed their potential to replace traditional, hazardous, volatile, non-polar solvents such as toluene. Each new candidate then demonstrated their suitability to replace these traditional solvents in solubility tests, despite being esters and ketones, each candidate demonstrated their similarity to traditional volatile non-polar solvents in terms of their solubility properties by their ability to dissolve natural rubber, a particularly low-polarity solute. This was reinforced by their performance in a model Menschutkin reaction and a radical-initiated polymerisation for the production of pressure-sensitive adhesives, where their performance was found to be similar to that of toluene. Importantly, a preliminary toxicity test (Ames test) suggested non-mutagenicity in all candidates. Each of the four candidates can be synthesised via a catalytic route from potentially renewable resources, thus enhancing their green credentials.

Catalytic conversion of ketones to esters: Via C(O)-C bond cleavage under transition-metal free conditions

Subaramanian, Murugan,Ramar, Palmurukan M.,Rana, Jagannath,Gupta, Virendra Kumar,Balaraman, Ekambaram

The catalytic conversion of ketones to esters via C(O)-C bond cleavage under transition-metal free conditions is reported. This catalytic process proceeds under solvent-free conditions and offers an easy operational procedure, broad substrate scope with excellent selectivity, and reaction scalability. This journal is

Acid-catalyzed oxidation of levulinate derivatives to succinates under mild conditions

Wang, Yuran,Vogelgsang, Ferdinand,Román-Leshkov, Yuriy

, p. 916 - 920 (2015/03/18)

Levulinate derivatives are an attractive platform for the production of renewable chemicals. Here we report on the oxidation of methyl levulinate into dimethyl succinate with peroxides under mild conditions using Br?nsted and Lewis acid catalysts. Selectivities to succinate and acetate derivatives of approximately 60 and 40 %, respectively, were obtained with strong Br?nsted acids in methanol. Although the molecular structure (i.e., carbon-chain length and branching around the C=O group) and the oxidant type affect the product distribution, solvent choice has the strongest impact on changing the location of oxygen insertion into the carbon backbone. Specifically, switching the solvent from methanol to heptane resulted in a decrease in the succinate/acetate ratio from 1.6 to 0.3. In contrast to Br?nsted acids, we demonstrate that the nature of the metal cation is responsible for changing the reaction selectivity of water-tolerant Lewis acidic triflate salts.
