Check Digit Verification of cas no

The CAS Registry Mumber 22610-63-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,2,6,1 and 0 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 22610-63:
(7*2)+(6*2)+(5*6)+(4*1)+(3*0)+(2*6)+(1*3)=75
75 % 10 = 5
So 22610-63-5 is a valid CAS Registry Number.

Synthesis and analysis of symmetrical and nonsymmetrical disaturated/monounsaturated triacylglycerols

Adlof, Richard O.,List, Gary R.

, p. 2096 - 2099 (2003)

Symmetrical disaturated triacylglycerols of the structure SUS, where S is stearic acid (18:0) and U is an unsaturated fatty acid, either oleic (O; 9cis-18:1), linoleic (L; 9cis, 12cis-18:2), or linolenic (Ln; 9cis, 12cis, 15cis-18:3), are important components providing functionality to interesterified fat blends and structurally modified oils. Nonsymmetrical triacylglycerols of the structure SSU can significantly change melting point and solid fat content profiles. To characterize the physical properties of pure and symmetrical and nonsymmetrical triacylglycerol mixtures, the same reaction sequence has been used to prepare multigram quantities of triacylglycerols SUS and SSU. Tristearin was converted to a mixture of mono-, di-, and triacylglycerols, and the 1,3- and 1,2-diacylglycerol fraction was isolated by silica column chromatography. The 1,3-diacylglycerols were removed by crystallization from acetone and esterified with the appropriate fatty acid to form the symmetrical triacylglycerols with >99% SUS structure. The more difficult to obtain 1,2-diacylglycerols were prepared by esterification of the enriched 1,2-diacylglycerol fraction (80-86% 1,2-diacylglycerols) remaining after removal of much of the 1,3-isomer by crystallization, but silver resin or silver nitrate impregnated silica gel chromatography was required to isolate the nonsymmetrical triacylglycerols. SSL and SSLn were prepared in purities of >98% by this procedure, but not SSO. Silver ion HPLC was found to be as accurate as, and more rapid than, lipolysis/gas chromatography for the determination of the isomeric purities of the synthesized triacylglycerols.

Boronic acid-promoted site-selective Fischer esterifications of sugar alcohols

Manhas, Sanjay,Lin, Yu Chen,Wang, Grace,Kyne, Luke T.,Taylor, Mark S.

, p. 5363 - 5367 (2019)

A protocol for selective monoesterification of glycerol and pentose alcohols with fatty acids is described, using phenylboronic acid as a phase-transfer reagent. Formation of arylboronic ester intermediates serves both to increase the solubility of the alcohol substrate in nonpolar organic solvent and to selectively protect diol groups, allowing for efficient and selective condensation with the aliphatic carboxylic acid. A phase-switching workup with basic aqueous sorbitol solution is used to cleave the boronic ester groups and to separate the boronic acid from the monoester product. The method provides an operationally simple means of access to a class of bio-derived products that have been broadly applied as food additives, components of cosmetic products and pharmaceutical formations, plasticizers, and non-ionic surfactants.

Kinetic and docking study of synthesis of glyceryl monostearate by immobilized lipase in non-aqueous media

Bhanage, Bhalchandra M.,Jawale, Priyanka V.

, (2021/12/21)

Glyceryl monostearate is extensively used as an emulsifier in many industries. Mono acylation of glycerol was carried out by utilizing immobilized Candida antarctica lipase B (Cal B) as a biocatalyst and vinyl stearate as an acyl donor. Different reaction parameters, such as selection of lipases from various sources (like Candida antarctica, Candida rugosa, and Mucor meihei) and their quantity, shaking speed, temperature, substrate concentration, and reusability were studied in detail to achieve excellent conversion. Overall, 98% conversion of glycerol was obtained at a mole ratio of 1:1 of glycerol to vinyl stearate, using 12 mg of immobilized Cal B at 45 °C for 3 h. The mechanism of the given reaction was anticipated based on the results of the Lineweaver-Burk plots. It was found that the reaction followed the Ping-Pong Bi Bi mechanism with inhibition of glycerol. As it was a kinetically controlled synthesis, different kinetic constants were estimated by non-linear regression analysis. The activation energy for Cal B was found to be 10.3 kcal/mol. Further, biocatalyst can be reused up to four catalytic cycles with an average four percent loss of activity. A molecular docking study was done to find out the confirmation of substrates and their binding positions in an enzyme. It was noticed that the reaction proceeds through acyl-enzyme complex formation followed by the transfer of that acyl group to another substrate.

Method for synthesizing high-content fatty acid monoglyceride and co-producing nano SiO2

-

Paragraph 0039; 0042; 0043, (2019/03/28)

The invention belongs to the field of fatty acid glyceride synthesis and nano powder preparation, relates to a method for synthesizing high-content fatty acid monoglyceride and co-producing nano SiO2,and particularly relates to a method for synthesizing fatty acid monoglyceride and co-producing the nano SiO2 by long-chain fatty acid and glycerinum. The method comprises the following steps of: using silicon tetrachloride to react with the glycerinum, so as to enable the glycerinum to be partially esterified to generate silicic acid glyceride; and performing an esterification reaction with fatty acid to generate fatty acid silicic acid glyceride; finally using high-activity (instability) of silicate ester, hydrolyzing in a mild condition, synthesizing the high-content fatty acid monoglyceride, and by-producing SiO2 powder in a nano state. So that a fatty acid monoglyceride product is high-selectively obtained and nano SiO2 powder is co-produced by a simple technology in the mild condition.
