A straightforward and cost-effective synthesis of a polymer-supported titanium alkoxide catalyst is reported. The described synthesis involves cheap, readily available and relatively non toxic chemicals, solvents and workup procedures. Efficiency and stability of the catalyst were tested in a laboratory-scale continuous flow reactor under equilibrium conditions over a month period. The average daily titanium leaching was estimated to less than 1% of the total amount of titanium engaged. To our knowledge, this result is the best obtained, to date, concerning the use of heterogeneous titanate for the catalysis of transesterification reactions.

Manganese, the third most abundant transition-metal element after iron and titanium, has recently been demonstrated to be an effective homogeneous catalyst in numerous reactions. Herein, the preparation of silica-supported MnII sites is reported using Surface Organometallic Chemistry (SOMC), combined with tailored thermolytic molecular precursors approach based on Mn2[OSi(OtBu)3]4 and Mn{N(SiMe3)2}2?THF. These supported MnII sites, free of organic ligands, efficiently catalyze numerous reactions: hydroboration and hydrosilylation of ketones and aldehydes as well as the transesterification of industrially relevant substrates.
METHOD FOR THE PRODUCTION PROCESS OF BUTYL METHACRYLATE

Paragraph 0028-0030, (2017/01/09)
The present invention relates to a preparation method of butyl methacrylate, which comprises the steps of: a) preparing butyl methacrylate through ester exchange reaction of n-butanol and methyl methacrylate in the presence of titanium tetrabutoxide catalyst; and b) removing the catalyst by adding glycerol to butyl methacrylate after the ester exchange reaction. The preparation method of butyl methacrylate in the present invention improves removal rate of residual solvents remaining after recovering the products after the ester exchange reaction, and has the catalyst removal process at low costs.COPYRIGHT KIPO 2016
