PROCESS FOR THE PRODUCTION OF PHOSPHOR ORGANIC COMPOUNDS |
摘要 |
A novel process is described for preparing phosphonites or phosphinites by reacting a product of a Friedel-Crafts reaction with alcohols or phenols and separating off the byproducts formed. The novelty is the aftertreatment with a protic compound, or with an oxide, hydroxide, (hydrogen) carbonate resp. (hydrogen) phosphate of a metal or with a nitrogen containing compound (as defined in claim 1), or with any combination of one or more substances of the above mentioned compound classes. Products having a low halide and aluminium content are obtained which are distinguished by an improved clear solubility and an improved action as stabilizer for polymeric materials. |
