The alkyl or alkenyl
side chain of these piperidines has 9, 11, 13, 15, or 17 carbons.
Advanced analytical characterisation of sodium type (waxy / soapy) deposits showed the potential involvement of alkenyl
succinic acids (like DDSA and hexadecenyl succinic acids (HDSA)) in the formation of sodium containing deposits .
glycoside and alkynyl glycosides could also be prepared by using triethylsilane instead of hydrogen as a reductant.
A review of paper sizing using alkyl ketene dimer versus alkenyl
As the electrochemical polymerization process continued, the dissociated dithiolate anions reacted with the terminal alkenyl
groups on the deposited layer to form C-S-C bonds.
Nonpeptide angiotensin II receptor antagonists: synthesis, biological activities, and structure-activity relationships of imidazole-5-carboxyliv acids bearing alkyl, alkenyl
, and hydroxyalkyl substituents at the 4-position and their related compounds.
The O and P prefixes indicate the presence of an alkyl or an alkenyl
ether substituent, respectively.
BASF has obtained a patent for a n aqueous coating formulation comprised of a substituted, branched polyethyleneimine, which is obtained by a process comprised of reacting a branched polyethyleneimine having a weight-average molecular weight of from 500 to 10,000 g/mol with a carboxylic acid derivative of formula (I) R--(C=0)X (I), wherein R is a C5 to C18 alkyl group or a C5 to C18 alkenyl
group, X is a halogen, a hydroxyl group, or a group R--(C=0)--O--, a molar amount of the carboxylic acid derivative in the reacting is from 3 to 10 mol percent of a molar amount of ethyleneimine employed in preparing the branched polyethyleneimine, the reacting is comprised of formation and removal of a byproduct HX, and the formulation is configured to coat a substrate that is comprised of tannin.
Studies of starch esterification: reactions with Alkenyl
succinates in aqueous slurry systems.
The co-ctystallizing agent is selected from the group consisting of fatty acid having a C16-22 alkyl, alkenyl
, alkylaryl or alkoxy moiety; fatty alcohol having a C16-C22 alkyl, alkenyl
, alkylaryl or alkoxy moiety; and mixtures thereof.
Freeman and Whenham (1975) reported approximately equal level of alkenyl
groups, and Kameoka et al.
The mild conditions required for hydrolysis and condensation of alkoxysilanes allow an enormous number of substituents (alkyl, aryl, alkenyl
