    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.

    摘要: A process for producing a dibromonitro compound represented by the general formula

    wherein R represents a hydrogen atom or a methyl group, which comprises condensing nitromethane with formaldehyde or acetaldehyde in the presence of an alkali, the amount of the aldehyde being at least 1.5 moles per mole of nitromethane; and thereafter without isolating the product, treating the reaction mixture with bromine to brominate the product.
