Definitions

  • phosphoryl chloride greater than a 5.0 : 1.0 ratio
  • the large excess of phosphoryl chloride favors the end capping reaction.
  • the excess phosphoryl chloride is easily distilled from the reaction mixture and recycled into subsequent batches.
  • an oligomeric di-monophosphate acid stabilizer conforming to the structure of formula (I):
  • n is greater or equal to 3.

Abstract

Le di-dichlorophosphate d'éther de polypropane a été obtenu par réaction d'éther glycol de polypropane avec un excès d'oxychlorure de phosphore. L'excès d'oxychlorure de phosphore a été distillé à partir du produit de réaction sous vide pour donner du di-dichlorophosphate d'éther de polypropane de haute pureté. Le di-dichlorophosphate d'éther de polypropane est un intermédiaire chimique polyvalent qui peut être mis à réagir avec des composés, tels que des acides carboxyliques, des alcools, des amines, des thiols, des sels métalliques et de l'eau, pour fabriquer des matériaux fonctionnels.
