A composition comprising: a) a primary lipid component obtainable as the reaction product of one or more carboxylic acids with at least one of glycerol and propylene glycol; b) a co-lipid component selected from at least one of phosphorus-containing lipids and hydroxylated carboxylic acid esters ...
Fe-ZSM-5 and Fe-zeolite β are available commercially and these materials were used with phenol, dichloroacetic acid, and imidachloprid as target molecules. The reactions were carried out in the laboratory and in a solar pilot plant. The influence of the zeolites can be summarized as follows:...
carboxylic acid. Thus, we prepared the corresponding methyl ester. To prevent any further racemization of the ester, we evaporated all the solvents and utilized the crude methyl ester of (S)-2-bromobutyric acid for the subsequent SN2 reaction with adamantly isocyanide under standard conditions. ...

A process for synthesizing long-chain phosphonic acid derivatives and thiol derivative is disclosed. One embodiment provides organic compounds which can form a self-assembled monolayer and are obtained by reaction of an olefin with a thiocarboxylic acid and subsequent hydrogenation to give the thiol, ...
