Abstract
1422259 Ring chlorination of 2,2-bis-[4-(2 - hydroxyethoxy)phenyl]propane BAYER AG 15 June 1973 [3 July 1972] 28592/73 Heading C2C [Also in Division C3] Halogenated polyalkylene glycol aryl ethers in which the halogen substitutes the benzene ring and hydroxyl groups remain unreacted are prepared by reacting elementary bromine and/or chlorine with a polyalkylene glycol aryl ether of the formula wherein R 1 denotes H, C 1-4 alkyl, methoxy, ethoxy, phenoxy, Cl or Br, R 2 denotes H, Me or Et, n is an integer of from 1 to 20, R 3 denotes a methylene, methylmethylene, dimethylmethylene, sulphone or ether group and p is 0 or 1. Preferred temperatures are 25‹ to 150‹ C. and preferred solvents are CHCl 3 , CCl 4 , tetrachloroethane or pentachloroethane. Optional catalysts are iron, iron-III-chloride, aluminium chloride, antimony-V-chloride, molybdenum-V- sulphide, tri-IV-chloride, iodine, iodo-I- chloride, pyridine, quinoline and isoquinoline. Examples describe the bromination or chlorination of 2,2-bis-[4-(2-hydroxyethoxy)-phenyl] propane. Uses.-The product may be incorporated as fireproofing components in polyester and polyurethane resins. Examples describe the preparation of non-inflammable polyurethane foams based on the above halogenated glycol ethers in admixture with tris-(dimethylaminopropylhexahydrotriazine), ortho- and paranonyl-2-dimethylaminomethyl - phenol, silicon stabilizer, a polyether of OH-number 650 prepared from a 1 : 1 ethylene oxide/propylene oxide condensate with ethylene diamine, a polyether of OH- number 180 prepared from propylene glycol and ethylene oxide, trichlorofluoromethane, diphenyl kresyl phosphate and either a polyisocyanate obtained by phosgenation of crude aniline-formaldehyde condensates or a prepolymer derived therefrom by reaction with the above propylene glycol ethylene oxide condensate.
