624-24-8 Usage
Description
METHYL VALERATE, also known as Methyl pentanoate, is the methyl ester of pentanoic acid (valeric acid) with a fruity odor. It is commonly used in fragrances, beauty care, soap, and laundry detergents at levels of 0.1 – 1%. In a very pure form (greater than 99.5%), it is used as a plasticizer in the manufacture of plastics. Additionally, it is utilized as an insecticide.

Air & Water Reactions
Highly flammable. Insoluble in water.
Reactivity Profile
METHYL VALERATE is an ester. Esters react with acids to liberate heat along with alcohols and acids. Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products. Heat is also generated by the interaction of esters with caustic solutions. Flammable hydrogen is generated by mixing esters with alkali metals and hydrides. METHYL VALERATE reacts with oxidizing agents, bases and acids.
Fire Hazard
METHYL VALERATE is flammable.
Flammability and Explosibility
Flammable
Check Digit Verification of cas no
The CAS Registry Mumber 624-24-8 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,2 and 4 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 624-24:
(5*6)+(4*2)+(3*4)+(2*2)+(1*4)=58
58 % 10 = 8
So 624-24-8 is a valid CAS Registry Number.

ZWITTERIONIC CATALYSTS FOR (TRANS)ESTERIFICATION: APPLICATION IN FLUOROINDOLE-DERIVATIVES AND BIODIESEL SYNTHESIS
-
Paragraph 0010; 0026, (2021/01/29)
An amide/iminium zwitterion catalyst has a catalyst pocket size that promotes transesterification and dehydrative esterification. The amide/iminium zwitterions are easily prepared by reacting aziridines with aminopyridines. The reaction can be applied a wide variety of esterification processes including the large-scale synthesis of biodiesel. The amide/iminium zwitterions allow the avoidance of strongly basic or acidic condition and avoidance of metal contamination in the products. Reactions are carried out at ambient or only modestly elevated temperatures. The amide/iminium zwitterion catalyst is easily recycled and reactions proceed in high to quantitative yields.

Paragraph 0082-0083; 0092, (2021/06/02)
The invention discloses a method for preparing carboxylic ester compounds by oxidizing and breaking carbon-carbon bonds of secondary alcohol compounds. The method comprises the following steps: adding a secondary alcohol compound, an additive and a nitrogen-doped mesoporous carbon loaded monatomic catalyst into a fatty primary alcohol solvent, putting into a pressure container, sealing, introducing oxygen source gas with a certain pressure, controlling the pressure of the oxygen source gas to be 0.1-1 MPa and the reaction temperature to be 80-150 DEG C, and obtaining a product after the reaction to be the carboxylic ester compound. The nitrogen-doped mesoporous carbon-loaded monatomic catalyst adopted by the invention is high in activity, the highest separation yield of the carboxylic ester compound as a reaction product reaches 99%, the method is wide in application range, the reaction conditions are easy to control, the catalyst can be recycled, the post-treatment is simple, and the method is suitable for industrial production.
