19693-78-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 19693-78-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,6,9 and 3 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 19693-78:
(7*1)+(6*9)+(5*6)+(4*9)+(3*3)+(2*7)+(1*8)=158
158 % 10 = 8
So 19693-78-8 is a valid CAS Registry Number.

Synthesis method of m-methoxybenzyl alcohol

-

Paragraph 0027; 0031-0033; 0041; 0042; 0046-0048; 0055; ..., (2021/06/26)

The invention discloses a synthesis method of m-methoxybenzyl alcohol. The synthesis method comprises the steps: (1) by taking ethylene glycol and m-chlorobenzaldehyde as raw materials and sulfuric acid as a catalyst, carrying out condensation reaction in a solvent to prepare ethylene glycol condensed m-chlorobenzaldehyde; (3) dissolving the ethylene glycol condensed m-chlorobenzaldehyde in an organic solvent to obtain a mixed solution; (4) adding a condensing agent into the mixed solution under a stirring condition, and heating for reaction to form a reaction system containing ethylene glycol condensed m-methoxybenzaldehyde; (5) evaporating to remove the organic solvent in the reaction system, then cooling, adjusting the pH value of the system, and carrying out phase splitting on the reaction system after the pH value is adjusted to obtain an organic phase I; (6) adding a catalyst and a metal reducing agent into the organic phase I, resolving acetal and reducing to obtain a reaction solution containing a crude product of m-methoxybenzyl alcohol; and (7) continuing to split phases of the reaction liquid to obtain an organic phase II, and washing, drying and rectifying the organic phase II to obtain refined m-methoxybenzyl alcohol.

supporting information, p. 5604 - 5607 (2016/11/17)

The development of an unprecedented chemoselective transformation has contributed to forming a novel synthetic process for target molecules. Chemoselective oxidation of aromatic acetals has been accomplished using a reusable palladium on carbon catalyst under atmospheric oxygen conditions to form ester derivatives with tolerance of aliphatic acetals and ketals.

experimental part, p. 131 - 135 (2009/09/30)

Various types of aromatic aldehydes were efficiently converted to their corresponding 1,3-dioxanes and 1,3-dioxolane with 1,3-propanediol and ethylene glycol, respectively, in the presence of catalytic amount of ZrO(OTf) 2 in acetonitrile at room temperature. The catalyst can be reused several times without loss of its catalytic activity. Very short reaction times, selective acetalization of aromatic aldehydes in the presence of aliphatic aldehydes and ketones, very mild reaction conditions, reusability of the catalyst, and easy workup are noteworthy advantages of this method.
