説明

Unsaturated acid and its esters can be polymerized by heating and with the use of proper catalysts. It was reported that oleic acid can be dimerized with BF3 or organoperoxide catalysts. The author found that oleic acid and its esters can be polymerized by the activated clay catalyst. This paper deals with the studies of polymerization of oleic acid and ethyl oleate with the catalyst. <BR>The effects of the amounts o catalyst and the reaction temperature on the yields of dimer and polymer, on the properties and structures of the products were studied. Besides the polymerization, such side reactions as decarboxylation, lactone formation, and isomerization were observed. Hydrogenation, accompanied with the dehydrogenetic dimerization, was also estimated from the formation of saturated acids. <BR>Under the reaction condition of 210°C and 2 hr, about 25% of dimer and 25% of polymers were formed from oleic acid with the use of 50 wt % of activated clay to oleic acid. The main diner was considered to have one double bond in its molecule, but the dimer which contains two double bonds was also formed by the selection of the reaction condition.
