PRODUCTION OF BIS(2,2,6,6-TETRAMETHYL-4-PIPERIDINO)SEBACATE

Title:

PRODUCTION OF BIS(2,2,6,6-TETRAMETHYL-4-PIPERIDINO)SEBACATE

Document Type and Number:

Japanese Patent JPH0267264

Kind Code:

A

Abstract:

PURPOSE: To obtain the title compound by subjecting 2,2,6,6-tetramethyl-4- piperidinol and a sebacic ester to ester interchange by using monobutyltin oxide and/or dibutyltin oxide alone or together as a catalyst.

CONSTITUTION: 2,2,6,6-Tetramethyl-4-piperidinol and a sebacic ester (e.g. dimethyl sebacate) shown by the formula (R is 1-8C alkyl) are subjected to ester interchange by using monobutyltin oxide and/or dibutyltin oxide having extremely high activity as an ester interchange catalyst and not causing problems in terms of yield, discoloration of reaction product, etc., alone or together as a catalyst to give bis(2,2,6,6-tetramethyl-4-piperidino)sebacate. This compound is useful as a light stabilizer of polymer materials.
