A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 79725-98-7, Name is (4-Oxo-5-(palmitoyloxy)-4H-pyran-2-yl)methyl palmitate, molecular formula is C38H66O6.

Synthesis and styrene copolymerization of novel trisubstituted ethylenes: 11. Halogen ring-substituted propyl 2-cyano-3-phenyl-2-propenoates
Novel trisubstituted ethylenes, ring-substituted propyl 2-cyano-3-phenyl-2-propenoates, RPhCH=C(CN)CO2C3H7 (where R is 4-chloro-3-fluoro, 2-fluoro-5-iodo, 2-fluoro-6-iodo, 2-trifluoromethyl, 3-trifluoromethyl, 4-trifluoromethyl, 2-trifluoromethoxy, 3-trifluoromethoxy, and 4-trifluoromethoxy) were prepared and copolymerized with styrene. The ethylenes were synthesized by the piperidine catalyzed Knoevenagel condensation of ring-substituted benzaldehydes and propyl cyanoacetate and characterized by CHN analysis, FTIR, H-1 and C-13 NMR. All the ethylenes were copolymerized with styrene in solution with radical initiation (ABCN) at 70 degrees C. The composition of the copolymers was calculated from nitrogen analysis, and the structures were analyzed by FTIR, H-1 and C-13 NMR. Decomposition of the copolymers in nitrogen (TGA) occurred in two steps, first in the 250-500 degrees C range with residue (0.5-3.1% wt.), which then decomposed in the 500-700 degrees C range.
