Kinetics of the Hydrolysis of Acetyl ChlorideThe hydrolysis of acetyl chloride in mixed solvent of acetone-water was investigated by means of an electrical conductance method. The temperature was varied ovCairns, Elton J.Prausnitz, J. M.Social Science Electronic Publishing...
Acceleration of the Hydrolysis of Organic Fluorophosphates and Fluorophosphonates with Hydroxamic Acids A series of hydroxamic acids were prepared by standard procedures from the corresponding esters with the exception of o-methoxybenzohydroxamic acid which was obtained from the acid chloride. Compounds ...
19. Three kinds of gemini anionic surfactants were synthesized through addition reaction, acylation reaction and hydrolysis from starting materials of octanoyl chloride, decanoyl chloride and lauroyl chloride. 分别以辛酰氯、癸酰氯、十二酰氯为原料,经加成、酰化及皂化等反应合成了3种双子型阴离子表面活性剂。
Rate constants of non-catalyzed of 3-acetyl-1,3-diphenyltriazene () and 3-(N-methylcarbamoyl)-1,3-diphenyltriazene () have been measured in the presence of salts (ammonium chloride, potassium chloride, lithium chloride, sodium chloride and bromide, ammonium sulphate, potassium sulphate, lithium...
1715 Inclusion of such cationic surfactants as benzyldodecyldimethylammonium chloride or tert-butyl-(2-ethoxyethyl)phenoxydimethylammonium chloride activates enzymes.1716 Saccharification can be accelerated when starch blended with the enzyme is subjected to malting. Saccharification usually involves alpha and ...
[4]arenes 3-5 were synthesized as racemate starting from the ethylation at 1.3-distal hydroxy groups of calix[4]arene 2 which has two phenyl groups at upper rim in AABB fashion, and then two remaining hydroxy groups were acetylated by treatment with acetyl chloride in the presence of NaH ...
Theoretical investigation of the stepwise hydrolysis of the [Re-3(mu-Cl)(3)Cl-9](3-) anion A detailed study of the stepwise substitution of the chloride ligands in the [Re3(mu-Cl)3Cl9](3-) (1) anion by water molecules is presented using theoretic......
The acetyl moiety may be stabilised in the small hydrophobic area composed of Ala332 and Thr358. Kinetics of Ac-SDKP hydrolysis by ACE. Kinetic analysis was performed to assess the selectivity and possible co-operativity of the N- and C-domains in Ac-SDKP processing. Individual N-...

Alkaline hydrolysis of gangliosides in butanol–aqueous tetramethylam-monium hydroxide yields a mixture of the derivatives lacking the acetyl group(s) and acyl chain.17 Acetylation of these compounds followed by purification yields a single-lipid-chain ganglioside derivative, which, in aqueous solution,...
