The preparation of higher fatty acids with an odd number of carbon atoms by the Arndt‐Eistert synthesis1 Pentadecanoic, heptadecanoic and nonadecanoic acid were prepared from respectively myristic, palmitic, and stearic acid by the Arndt-Eistert synthesis. The use of the Wilds and Meader variation ...
The structure of the most common class of phospholipids, phosphoglycerides, is based on glycerol, a three-carbon alcohol with the formula CH 2 OH–CHOH–CH 2 OH. Two fatty acid chains, each typically having an even number of carbon atoms between 14 and 20, attach (via a dual esterificati...
Esters of glycerol with linear fatty acids, saturated or unsaturated, with an evennumberof carbonatomsfrom 8 to20inclusive and/or with adipic, citric, 12-hydroxystearic (oxystearin), ricinoleic acids Estri glicerola z linearnimi maščobnimi kislinami, nasičenimi ali nenasičenimi, s so...
An aromatic molecule containing the same number of carbon atoms (1,4-dimethylbenzene) has a RON of 146. The octane numbers of straight-run (virgin) gasolines can be improved by converting paraffins to isoparaffins or aromatics. Two processes are used for this: one (isomerization) for ...
Esters of glycerol with linear fatty acids, saturated or unsaturated, with an even number of carbon atoms from 8 to 20 inclusive and/or with adipic, citric, 12-hydroxystearic (oxystearin), ricinoleic acids EurLex-2 are $g(b)-hydroxy-substituted alkyl residues with 8-30 C-atoms and/or...
If so desired, the carboxylic acids in question may be used as anhydrides or in the form of an ester, e.g., an ester of an alcohol having 1-4 carbon atoms. In addition, the alkyd resin comprises di- or polyvalent hydroxyl compounds. Examples of suitable divalent hydroxyl compounds are ...
Almost all of their molecular structures contain some of the special atoms such as N, O, S and P atoms, which could form a protective film on the metal surface, preventing most metal from dissolving in the acid solution [4,5]. Among all of the organic corrosion inhibitors, imidazoline ...
An independent claim is included for a diesel fuel comprising a hydrocarbon resulting from distillates of 180-350 [deg] C boiling point and the component comprising at least a saturated ester of more than 16 carbon atoms and preferably the stearic ester (>=0.5 wt.%).古田 智史...
The number of carbon atoms in the fatty acid portion of the ester compound represented by formula (I) is 6 to 12 and preferably 6 to 8 for the substituent "R1 " and 4 to 10 and preferably 4 to 6 for the substituent "R2 ". If the number of carbon atoms for the substituents is la...
