  摘要：

  AbstractIn the extraction of oils from seeds of the genus Coriandrum, GC separations of petroselinate from oleate often gave poor resolution of these two isomers. Oleic and petroselinic acids were esterified with a series of alcohols (methanol, ethanol, 1‐propanol, 2‐propanol, 2‐methyl‐1‐propanol, 1‐butanol, 3‐methyl‐1‐butanol, and 2‐ethyl‐1‐hexanol). GC resolution of the Δ6 from the Δ9 and Δ11 octadecenoates was examined for all ester derivatives on a polar phase column. The Δ6 and Δ9 isomers were unresolved as methyl esters; however, the 2‐ethyl‐1‐hexyl esters gave baseline separation of all three isomers under temperature programming conditions. When isothermal conditions were optimized for each ester, separation of these isomers was possible with good resolution values (>89%) for all the alcohols except methanol, which had a partial resolution of 51%. The rates of esterification of all the alcohols were determined for reactions with both oleic acid and triolein using potassium hydroxide as the esterification catalyst. Methanol gave the largest rate constant in both acid and oil esterification reactions with a rate constant 10‐fold better than all of the other alcohols. Based on rates of reaction, resolution of petroselinate from oleate, and removal of residual alcohol, the ethyl ester derivative appears to be the best choice for seed oils containing petroselinic acid.

  An exemplary method for set retarding the surface of a mortar or concrete material, comprising applying to the surface of a mortar or concrete, or to the inner surface of a mold for forming the mortar or concrete, a non-petroleum based hot melt coating composition which is heated to assume a flowable or sprayable form, and allowing the hot melt coating composition to cool to ambient temperature whereby the composition forms a solidified membrane, and thereafter removing the membrane using pressurized water. Preferably, the hot melt coating composition contains at least one agent operative to retard the setting of the mortar or concrete, and optional finely divided particulate materials, light-reflective pigments, or mixtures thereof.
