The Effect of Adding Mg-Zn/Al Hydrotalcite on the Decarboxylation Product of Hydroxy Pelargonate Soap

Pelargonic acid is a by-product of the ozonolysis reaction oleic to azelic acid. decarboxylation process removing carboxyl group (-COO-) from pelargonic (C9H18O2) produce n-octane (C8H18) hydrocarbons, which are main hydrocarbons that make up gasoline. The parameter in gasoline octane number. number 15, considered low, while good desired have high To convert straight-chain alkanes and alkenes into branched alkenes, an isomerization can be carried out on vapor-cracking products using solid catalyst. Transition metals their compounds used as catalysts. able change oxidation state, create complex compounds, absorb other substances metal surface, activate these substances. transition this study Zn Al. stages research were preparation Mg-Zn/Al hydrotalcite base, manufacturing hydroxy pelargonate soap, soap. results found highest product gain, namely 64.76%, occurred when = 5:5:2 was 300% excess. selectivity 2.16% use excess 3:3:2 hydrotalcite. A low Al/Mg/Zn ratio 2:10 increase yield; 2:6 lower freezing point.
