1 In contrast, the unconjugated, carboxylic, bile acids are easily precipitated by calcium phosphate. 2 The copious benzene rings and potential carboxylic acid groups in coal suggest that these transformations might not be too difficult. 3 The esterification mechanism of unsaturated carboxylic acid was analyzed. 4 One exception is the decarboxylation of aromatic carboxylic acids. 5 Twelve different thioxanthone carboxylic amides derivatives are prepared. 6 Carboxylic acid esters are important chemical raw materials. 7 A method of hydrogenating the nitrile containing carboxylic acid acids obtained by above hydrocyanation to produce amine containing carboxylic acids is also disclosed in this invention. 8 A oxazolidine carboxylic acid tanning agent-MOCA has been synthesized by condensing DL-threonine with formaldehyde. 9 of 2, 2 - dimethylthiazolidine 4 - carboxylic acid and its hydrochloride in microwave. 10 Stearic acid (octadecanoic acid) A saturated carboxylic acid, which is widely distributed in nature as the glyceride ester. 11 Polyethylene glycol unsaturated carboxylic esterified macromer; Polycarboxylic acid type water-reducer; Molecular designing; High performance. 12 Lactic acid: Carboxylic acid found in certain plant juices, in blood and muscle, and in soil. 13 The petroleum carboxylic acids in two distillates of North Sea crude oil were separated by the extraction with column chromatogram and anion exchange resin. 14 A solidification matrix includes a straight chain saturated carboxylic acid salt, sodium carbonate, and water. 15 The alkali-treated "cage" polyamidoxime adsorbent (BCAO) possesses the high adsorptivity for the adsorption of carboxylic acids. 16 Experiment results indicated that HZ-type solid acids were ideal catalysts for direct esterification of straight chain carboxylic acids and primary alcohols. 17 It was prepared by the reaction of 12 H - dibenzo [ d , g ] [ 1,3 ] dioxocin - 6 - carboxylic acid with acetoxime. 18 The study result indicated that the white powdered particles were mainly composed of calcium salts of long chain carboxylic acid, namely the calcium stearate. 19 They are usually prepared from equivalent amounts of glycols and dibasic carboxylic acids, which undergo condensation polymerization to produce the polyester and water. 20 The most commonly used method for the covalent binding of biomolecules onto 1-D nanostructures is through the diimide-activated amidation of carboxylic acid terminated nanostructures. 21 The alkali - treated cage adsorbent ( BCAO ) possesses the high adsorptivity for the adsorption of carboxylic acids. 22 R 2 is H , amino acid residues, alkyloxyethyl formyl, organic carboxylic acid acyl , phosphoryl, and alkyl. 23 Effects of process conditions such as content of composite carboxylic acid, initial current density and anodizing time on properties of film were studied. 24 An improved synthetic route for 4 ? ? heptoxybiphenyl 4 carboxylic acid was studied. 25 Eventually, the researchers found that two samples - segments 2 - methyl alcohol and indole ring - 6 - carboxylic acid. 26 FD is a kind of re tanning agent condensated with glyoxal, formaldehyde, carboxylic acid and urea. 27 Industrial lignosulfonate is modified to graft carboxy by the free radical copolymerization reaction to synthesize a kind of scale inhibitor-the carboxylic lignosulfonate. 28 Synthesis of acyl azide from aldehyde, or acylhydrazine, or carboxylic acid , or acyl chloride, or anhydride, or ester is introduced in this paper. 29 The yield of O-alkylation of 2,5-dimethylphenol with the monohalogen carboxylic esters is above 81%. 30 Proteolytic enzymes catalyze oligomerization of the. alpha . - hydroxy carboxylic acid and . alpha . - amino acid.
