Benzoate Ester as a New Species for Supramolecular Chiral Assembly

In this work, a benzoate ester molecule of dodecamethylnonacosane-2,28-diyl dibenzoate (DMNDB) has been discovered as a new species to aggregate into chiral nano-assemblies. In tetrahydrofuran (THF)/water system, the benzoate ester...

Development of new ecofriendly detergent/dispersant/antioxidant/antiwear additives from l-histidine for biolubricant applications

Novel histidine Schiff base ester molecule containing a detergent like-framework used as multifunctional additive in a polyol base fluid.

6-Chloro-3-pyridylmethyl 4-aminobenzoate benzene solvate

The ester molecule of the title compound, C13H11ClN2O2·C6H6, is not planar, with a dihedral angle between the benzene and pyridine rings of 15.2 (3)°. Two ester molecules are connected by intermolecular N—H...N hydrogen bonds, forming a dimer.

Cometathesis of methyl oleate with α-olefins

Cometathesis of methyl oleate with 1-hexene or with other α-olefins affords two new esters and two new olefins. In the case of 1-hexene these products are methyl 9-decenoate, methyl 9-tetradecenoate, 1-decene and 5-tetradecene. At the same time, the formation of the esters and olefins with shorter chains(i.e. decene and decenoate) is distinctly preffered. Obviously, the transfer of methylene group from the alkene to the ester molecule is much easier than that of the alkylidene moiety. The non-stoichiometric course of cometathesis is associated with the carbene mechanism of the reaction.

Excess molar enthalpies of binary mixtures containing esters of fatty acids

Excess molar enthalpies [Formula: see text] at 310.15 K and 101.32 kPa, have been determined for the binary mixtures: lauric acid ethyl ester +, stearic acid ethyl ester +, oleic acid ethyl ester +, linoleic acid ethyl ester + n-hexadecane, + toluene, or + ethyl alcohol, and elaidic acid ethyl ester + n-hexadecane or + toluene.The results show that HE of ester + n-hexadecane mixtures increases with decreasing chain length and with increasing unsaturation of the ester molecule. Ester + toluene mixtures are slightly exothermic and ester + alcohol are strongly endothermic, with [Formula: see text] values ranging from 1535 to 1740 J mol−1 at the maximum.
