Controlling product composition of metathesized triolein by reaction concentrations
Triolein was used as a model material to investigate the effect of concentration on self metathesis of vegetable oils. The metathesis reaction using Grubbs' second generation catalyst (used at a level of 2.5 mol % of triolein) was carried out at 38 °C usi

A new catalyst for the preparation of oleate of glycerin
In this investigation sulfate promoted titanium oxide (SPTO) is used to prepare oleate of glycerin, an excellent internal lubricant for manufacturing transparent sheet materials of polyvinylchloride (PVC).Experimental results show that the occasional saponification caused by the conventional sodalye catalyst for preparing oleate of glycerin can be avoided completely.SPTO can be used repeatedly without any special treatment.Its activity is comparable with that of sodalye.Also the use of SPTO can produce the desirable product composition.SPTO is likely to become a new catalyst for the production of oleate of glycerin.
