Method of producing the 4,4- (isopropylidenedithio) -bis- (2,6-di-t-butylphenol)

摘要

Procedure of obtaining the 4,4 '- (isopropilidenditio) - bis - (2,6 - Di - T - butylphenol).2.6 - di tert butifenol is reacted with acetyl chloride to form the corresponding acetyl phenol, which reacts with the acid clorosulfonico to Give 4 - chlorosulfonyl - 2.6 - ditercbutilfenol, which, in turn, is reduced to the corresponding thiol, The 4 - mercapto - 2.6 - ditercbutilfenol, LITHIUM ALUMINIUM HYDRIDE.Two Molecules of 2 - mercapto - 2.6 - diterc Butyl phenol was Condensed with acetone Molecule to form the corresponding tioacetal, 4,4 '- (isopropilidenditio) - bis (2,6 di TERT butylphenol).
