    Abstract: Phosphorus acid-aryl ester-amides of formula (I) and phosphorous acid-aryl ester-amide-halides of formula (II) are both claimed as are also (i) prepn. of (I) by reacting (II) with a specified Gringard cpd.; (ii) prepn. of (II) by reacting an appropriate dihalide with a specified amine; and (iii) use of (I), alone or together with a phenolic antioxidant, in the stabilisation of plastics. n = 1 or 2; R1 = (i) when n = 1, phenyl (opt. with 1-3 substits.), benzyl, alpha-Me-benzyl or alpha,alpha-di-Me-benzyl, or naphthyl (opt. substd. with 1-5 substits.) where at least one of the substits is 1-8C alkyl-oxy or -thio or 6-10 aryl or aryloxy or halogen of atomic no. 9-35 and the remainder (excluding the naphthyl residue) can be a non-aromatic 1-8C hydrocarbon residues; (ii) when n = 2, phenylene opt. substd. with up to 2 non-aromatic 1-8C hydrocarbon residues, etc., R2 = non-aromatic 1-8C hydrocarbyl, aryl or opt. substd. arylmethyl with the aryl having 6-10C; R3 = H or 1-18C alkyl-oxy or -thio, or as per R2; and R4 and R5 = 1-22C alkyl, 2-21C oxa- or thia-alkyl, 3-18C alkenyl or alkynyl, 3-24C alkoxy-carbonylalkyl, 5-12C cycloalkyl, 6-14C aryl, etc., and X = Cl or Br. USE/ADVANTAGE - (I) can be used directly for polymer stabilisation without the need to isolate it in a pure form.

    Abstract: The prepn. is claimed of phosphorous acid aryl esters of formula (I). Some of these (I') are novel cpds. and are claimed as such, with the use of (I') as stabilisers for (pref. synth) resins also being claimed. The prepn. of (I) comprises (1) reacting a halohydrocarbon of formula (R1-(Hal)n (Hal = halogen of atomic wt. at least 35) with at least a molar amt. of Mg to give a Griguard cpd. R'(MgHal)n; and (2) reacting the Grignard cpd. with a phosphoric bisaryl ester of formula (I: R' = Hal and n = 1). -A- is non-existent or is a direct link, n = 1 or 2; R' = (a) when n = 1, 1-18C non-aromatic hydrocarbon, phenyl (opt. contg. 1-3 substits), alpha-Me-benzyl, etc. (b) when n = 2, phenylene (opt. substd. by 1 or 2 non-aromatic 1-8C hydrocarbon) etc. R2 = non-aromatic 1-18C hydrocarbon, aryl, aryl(m)ethyl or arylisopropyl where aryl is of 6-10C; and R3 = H or as for R2.

    New and known di:aryl - with tetra:alkyl di:phosphinite cpds., are prepd. as stabilisers for plastics by reacting di:aryl halo-phosphonite with grignard cpd.

    Abstract: New phosphonites (I) have formula (1) R1, when monovalent = Ph, or PhCH2 with 1-3 substits. alpha- methyl or alpha, alpha-dimethylbenzyl, naphthyl opt. with 1-5 substits. which are non aromatic hydrocarbon gp. 1-8C alkoxy or alkylthio, 6-10C aryl or aryloxy, or halogen of atomic no. 9-35 or, when divalent = phenylene opt. substd. by 1 or 2 1-8C non aromatic hydrocarbon gp. or naphthylene opt. substd. by 1 to 4 1-8C hydrocarbon gps. R2 = 1-18C nonaromatic hydrocarbon gp. 6-10C aryl, 6-10C aryl-methyl 6-10C aryl-ethyl or 6-10C aryl-isopropyl, R3 = H or R2, excluding cpds. where n = 1, R1 = Ph and R2= R3 tert, Bu or tert, octyl or alpha -dimethylbenzyl, or R2 = tert, Bu and R3 = H, or R2 = tert, octyl and R3 = Me. USE/ADVANTAGE - Alone or with phenolic antioxidants for stabilising plastics esp. polymerisation plastics (claimed) new and known (I) are obtd. readily, in high yield and purity.

    Abstract: A process for the production of the alpha -crystalline modification of a compound of formula (I), comprises dissolving (I), in the form of its melt, or the amorphous solid-phase modification or the beta -crystalline modification in a 3-7C short-chain ketone (II) at 40-100 degrees C, and then crystallising by cooling to room temperature.
