DOCUMENT TYPE: Journal CA Section: 36 (Plastics Manufacture and Processing) Di-(3,5-di-tert-butyl-4-hydroxy)benzyl ether (I) [6922-60-7], di-(3,5-di-tert-butyl-4-hydroxybenzyl) oxalate [54850-16-7] and di-(3,5-di-tert-butyl-4-hydroxybenzyl) hippurate [67184-86-5] with 2 reactive centers are prepd. and used as antioxidants for low-d. polyethylene [9002-88-4]. Thus, I was prepd. by the reaction of 2,6-di-tert-butylphenol [128-39-2] with HCHO and HCl via formation of dichloromethane ether intermediate. The structure of the prepd. inhibitors was confirmed by IR spectroscopy.

CODEN: SNPAAQ. ISSN: 0400-9525. DOCUMENT TYPE: Journal CA Section: 36 (Plastics Manufacture and Processing) Bis(3,5-di-tert-butyl-4-hydroxybenzyl) ether (I) [6922-60-7] and 3,5-di-tert-butyl-4-hydroxybenzyl hippurate (II) [54850-15-6] are prepd., their physicomech. properties are detd., and they are used as antioxidant for polymers. Thus, I was prepd. by a reaction of paraformaldehyde and HCl with 2,6-di-tert-butylphenol [128-39-2]. Bis(3,5-di-tert-butyl-4-hydroxybenzyl) oxalate [54850-16-7] and II were prepd. by the reaction of alkali metal salts of the resp. acids with 3,5-di-tert-butyl-4-hydroxybenzyl chloride [955-01-1] in an org. solvent. I, which was compatible to Stablizer 22-46, had the highest antioxidative power.
