摘要：
Novel nitro containing esters of a phenylpropionic acid having the geral formula
wherein R, and R 2 are lower alkyl or a radical of the structure
and "X" 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.
