Abstract: New bis-imidazolinium salts are of formula (I): (where R is an (un)-satd. linear or branched 7-29, pref. 11-17C (hydroxy)-alkyl gp.; Z is an (un) satld. 2-12C alkylene gp., opt. with OH, CO, CN or Cl substit, or with -O-, -S- or -NR- in the chain, R being H or 1-4C alkyl; X is an anion, pref. Cl or Br). (I) are prepd. by heating approx. equimolar amts. of aminoethylhydroxyethylamine and 8-30 (12-18)C fatty acid(s) for 1-10 hrs. in the absence of air at 130-220 degrees C to an amide, then heating for 10-12 hrs. in the presence of a water eliminating agent under reduced pressure at 180-230 degrees C and reacting for 1-15 hrs. in the absence of air with ca. 0.5 mole (un)satd. 2-12 C alpha, omega-dichloro-or-dibromo-cpd., opt. with OH, CO, CN or Cl substit. or with -O-, -S- or -NR- in the chain, at 40-200 degrees C. 0.1-2.5% (I), w.r.t. the wt. of the fibres, is used as a retarder (to aid levelling) in the dyeing of polyacrylonitrile fibres or (mixed textiles with basic dyes. Lower concns. of (I) are required and the dye absorption phase is shorter.

Abstract: Prodn. of level dyeings on acrylic fibres with basic dyes is achieved by use of title cpds. of formula (I): (where R1, R3 and R4 are H or 1-4C alkyl; R2 is 1-4C alkyl or benzyl; and X is residue of an inorg. acid or a 1-3C alkylsulphuric acid), pref. by treating the dyed goods in a blank bath.

Abstract: New ammonium salts (I) of N-alkyl-N' aminoalkylureas have formula R-NH-CO-NH-(CH2)x- circled positiveNMe2R' Circled negative in which R is 16-20C alkyl; R' is CnH2n+1 (pref. n = 1-4), Ph or PHCH2; Circled negative is Clcircled negative, 1/2SO4-2, 1/2CO32-, C104- or MeSO3-; x = 2-5). (I) can be prepd. by reacting half-quaternised alkylenediamine derivs., e.g. H2N.CH2CH2NMe3Cl, and an alkyl isocyanate, e.g. stearyl isocyanate, or by reacting a diamine with one prim. and one tert. amino gp., e.g. Me2--N(CH2)3NH2 or Et2N(CH2)3.CH(NH2)Me, with an alkyl isocyanate, followed by quaternisation with an alkylating agent, e.g. Me2SO4 or MeCl. (I) are used in aq. soln. for treating textiles, giving an antistatic finish for polyacrylonitrile and a soft finish for regenerated celluose, cotton, polyester and nylon.

Abstract: An inert solid carrier is impregnated with an aq. surfactant consisting of a reaction product (A) of a sat. or unsat. 12-24C fatty acid and an at least equimolar amount of N-beta-hydroxy ethyl ethylene diamine. Molar ratio is usually 1:1-1.5. The carrier is pref. sand, which is impregnated with 500-5000 ppm (A). The carrier is scattered on oil spills on the surface of water, in amounts of 0.5-2 wt. parts per part oil, to absorb oil and sink to the bottom. Large amounts of oil can be quickly and economically cleared without causing ecological damage.

Abstract: 1455505 Antistatic treatment of shaped articles BASF AG 28 Feb 1974 [1 March 1973] 9057/74 Heading D1P Shaped articles are of organic polymeric material, e.g. textiles, rendered antistatic by treatment with a compound of general formula where R and Q independently are hydroxyalkyl (2-3C), alkyl (1-4C) or benzyl and Q can also be the radical in which A is alkylene (216C), and X (-) is an organic or inorganic anion, or the n-th part of an n-valent, such anion (n being an integer greater than 1) preferably chloride or methosulphate. Preferably Q is methyl or ethyl. The surface treated may be a textile of natural or synthetic high molecular weight material. The compound may be applied by dipping, or spraying. An example relates to treating a polyamide fabric with a 0.05% strength solution of N - methyl - tri - (2 - hydroxyethyl) - ammonium chloride at a liquor ratio of 30:1 after which the fabric is dried and thermoset at 180‹-200‹C.
