    CN103030843A - Compound antioxidant for producing butadiene

    The invention provides a compound antioxidant for producing butadiene synthetic rubber and an application of the compound antioxidant. The compound antioxidant is compounded by 4-hydroxy-3,5-di-tert-butyl-hydrocinnamate or 4-hydroxy-3,5-di-tert-butyl-phenylpropionic acid C7-9 mixed alcohol ester and 2-methyl-4,6-bis[(octylthio)methyl] phenol and thiodipropionic acid bi-isotridecyl alcohol

    1,3-Butadiene (/ˌbjuːtəˈdʌɪiːn/) is the organic compound with the formula (CH 2 =CH) 2. It is a colorless gas that is easily condensed to a liquid. It is important industrially as a monomer in the production of synthetic rubber. The molecule can be viewed as the union of two vinyl groups. It is the simplest conjugated diene.

    Understanding the Composition of a Nitrile (Buna-N) Rubber

    Acrylonitrile Butadiene Rubber (NBR) or Nitrile rubber is one of the most popular compounds for automotive applications. It also is well known as Buna-N.This name came from one of the first base polymers patented in 1934, therefore people commonly use this name for all classes for Nitrile to this day.
