917-58-8 Usage

Chemical Properties

solid

Uses

Potassium Ethoxide is a solvent for the laboratory and industry in the manufacture of alcohol, pharmaceuticals, perfumery, and in other organic synthesis processes.

Flammability and Explosibility

Highlyflammable

Check Digit Verification of cas no

The CAS Registry Mumber 917-58-8 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 9,1 and 7 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 917-58:
(5*9)+(4*1)+(3*7)+(2*5)+(1*8)=88
88 % 10 = 8
So 917-58-8 is a valid CAS Registry Number.

A series of amino acid-derived chiral benzylthio alcohols have been prepared and characterized. A chiral mercapto alcohol derived from S-leucine has been used to form three chiral 2,4-disubstituted 1,3-oxathiolanes. One of these has been oxidized to the S-oxide and another to the S,S-dioxide. The cis and trans isomers have been characterized by 1H NMR in each case and it appears that thermal epimerisation at C-2 is possible at the sulfoxide oxidation state. The X-ray structure of major trans diastereomer of 2-phenyl-4-isobutyl-1,3-oxathiolane S,S-dioxide shows an envelope conformation with oxygen at the flap and an internal angle at sulfur of just 93.8°. This compound fragments upon flash vacuum pyrolysis at 700°C to give SO2, benzaldehyde and 4-methylpent-1-ene.

Preparation method for low residual granular sodium alkoxide or potassium alcoholate

-

Paragraph 0029-0030, (2017/01/17)

The invention provides a preparation method for low residual granular sodium alkoxide or potassium alcoholate. The method includes using sodium or potassium and alcohol as raw materials, mixing the mixture with a solvent, reacting in inert gas atmosphere by using a microwave heating method, and removing the residual alcohol and solvent in the presence of microwave after the reaction to get the granular sodium alkoxide or potassium alcoholate. The microwave frequency is 2450 +/- 50 MHz. The method can prepare sodium alkoxide or potassium alcoholate with low residual solvent, and the prepared sodium alkoxide or potassium alcoholate is large granular solid, so that the development from powdered product to granular product can be realized, and the problems of residual solvent and potential risk troubled human for a long time can be overcome.
