Abstract: Alkylphenols are manufactured by reacting phenols with olefins, stripping the reaction mixture by means of an inert gas, cooling the phenol-containing gas mixture and removing the unconverted phenol. The products are starting materials for the manufacture of dyes, pesticides, pharmaceuticals, emsulfiers, dispersing agents, stabilizers, antioxidants, plasticizers, corrosion inhibitors, disinfectants, seed dressings, stabilizers against ageing, crop protection agents and scents.

Abstract: Halogenated poly(benzylene)derivs. of formula (I) are new (where X is Cl or Br; R is 1-4C alkyl; A is CH2Cl, CH2Br or CH2OH; a = 1-4; b = 0-3; a+b = 1-4; n = 3-1000). Pref. cpds. have X is Br; R is CH3; a=1-3; b=1-3; n=5-500. (I) are made by oligomerisation of an Rb-substd. benzyl halide (II) with a Friedel-Crafts. catalyst, pref. in satd. halohydrocarbon solvent, then treatment with X2. (I) are flame-proofing agents for thermoplastic polymers, esp. polyamides, linear polyesters, styrene polymers and polyolefins. (I) are compatible with thermoplastics having no effect no their mechanical properties, and unlike known oligomeric flame retardants are simple to prepare.

Abstract: Prodn. of o-benzyltoluenes (I) of the formula A-B (in which A has the formula and B has the formula the R gps. are independently H or halogen and The R' gps. H, halogen or aliphatic or aromatic gps.) involves reacting o-xylyl halides (II) of the formula A-X (in which X is halogen) with benzenes (III) of the formula H-B in the presence of O-contg. cpds. (IV) of Al and Si. Reaction can be carried out (dis)continuously at 50-250 degrees C and press. up to 15 bar. It is pref. to operate without a solvent. (IV) pref. is an aluminosilicate with 1-95 mole Al2O3 per mole SiO2 and is used in amt. of 0.1-15 wt.% w.r.t. (II). (I) are valuable starting materials for the prodn. of anthracene, anthraquinone and their derivs. The process is simple and cheap, free from trouble and corrosion problems and gives (I) in good yields and purity, even at low reaction temps. Readily available starting materials are employed and no multistage syntheses are need for their prodn. The formation of sulphonation prods. is avoided and the protection of the environment is improved. In an example an o-benzylchlorotoluene isomer mixt. was obtd. in 87% yield from chloro-o-xylyl chlorides and benzene by heating 4 hrs. at 145 degrees C and 11 bar in the presence of Al silicate (10 wt.% Al2O3).
