Steps:
3 EXAMPLE 3 Synthesis of octadec-9-enedioic acid
EXAMPLE 3 Synthesis of octadec-9-enedioic acid Compounds Used: 90% pure oleic acid, ethylene, and ruthenium-based catalyst of type HG-SIPr. The protocol of example 2 is repeated identically with the catalyst HG-SIPr. (0098) The weight percentages of the compounds forming the solid obtained are as follows: [table-us-00004-en] TABLE 3 wt % HG-SIPr 1-decene 3.5 9-DA 6.4 9-octadecene 14.9 Oleic acid 3 Elaidic acid 17.7 D18:1 Z 2.5 D18:1 E 35.8 D18:1 total 38.3 The proton NMR analysis shows that the mass yield of the reaction is 81.6%.
