HINDERED PHENOLIC NITRO COMPOUNDS AS ANTIOXIDANTS

摘要

Novel nitro containing esters of a phenylpropionic acid having the geral formula …… wherein R1 and R2 are lower alkyl or a radical of the structure …… and " chi " represents a tertiary butyl radical can be prepared by reacting a propionic acid chlorid of the formula …… with the corresponding nitroalkanols of the formula …… …These esters stabilize organic material as polyolefines normally subject to oxidative deterioration and can be a component of a stabilizer composition, the other component being a dialkyl thiodipropionate.
