标题:Novel dibasic acid salts and their synthesis
发明人：SCHACHT ETIENNE; CROMMEN JAN
权利人:ETHYL CORP
摘要:The protecting group, Z, of protected alpha-amino acid esters of the formula n n Z--NH--CH(R.sub.2)COOCH(R)COOR.sub.1 n n is removed in the presence of a dibasic acid such as oxalic acid. This results in the formation of a new type of salt of an amino acid ester which may be represented by the formula ##STR1## In the above Q is a divalent hydrocarbyl residue of a dibasic acid, R is a hydrogen atom or hydrocarbyl group, R 1 is a hydrocarbyl group, R 2 is a hydrogen atom or hydrocarbyl group, and p is zero or one, preferably zero. When p is zero, the salts are oxalate salts. When p is one, the salts are salts of other dibasic acids. The salts (II) are useful as reactants in the synthesis of amino-acid substituted phosphazene polymers.

标 题 :Emulsifier-free carboxylated nitrile rubber latex
发明人：MULLER PASCALE FRANCINE JEANNE
权利人:GOODYEAR TIRE & RUBBER
摘要:Carboxylated nitrile rubber latices are used in a wide variety of industrial applications, such as in the manufacture of gloves, non-woven fabrics, masking tape and an array of other products. Carboxylated nitrile rubbers are conventionally synthesized by emulsion polymerization. The need for an emulsifier in the synthesis of carboxylated nitrile rubber can be eliminated by practicing the process of this invention. The present invention more specifically discloses a process for the synthesis of carboxylated nitrile rubber latex which comprises the steps of (1) initiating the terpolymerization of 1,3-butadiene, acrylonitrile and methacrylic acid in an aqueous polymerization medium by the addition of potassium persulfate and a potassium persulfate co-initiator, wherein the terpolymerization is initiated in a reactor that is at least 60 percent full, (2) allowing the terpolymerization to proceed at a temperature which is within the range of about 25°C to about 80°C until a solids content of at least about 20 percent is attained to produce a seed polymer latex, (3) adding additional 1,3-butadiene, acrylonitrile and potassium persulfate to the seed polymer latex over a period of at least about 1 hour to produce a second polymerization medium and (4) allowing the polymerization to continue in the second polymerization medium for at least 0.5 hour to produce the carboxylated nitrile rubber latex.

标 题:Explosion-proof 1-dimethylamino-3-dimethylimino-2-arylprop-1-ene salts, process for their preparation, and their use
发明人：MUELLER INGRID; HEMMERLING WOLFGANG; WINGEN RAINER
权利人:HOECHST AG
摘要:The invention concerns the preparation of explosion-proof trimethine salts which are only slightly soluble in water and have the formula (I), in which: R is an aryl or a heteroaryl group, which may contain one or more substituents, and X is an anion-equivalent of a non-oxidizing acid group which is inert with respect to trimethine cation and forms trimethine salts which are only slightly soluble in water, by formylation of compounds of the formula (II): R-CH2?-COOH, in which: R has the same meaning as in formula (I), under the conditions of the Vilsmeier-Haack reaction, followed by aqueous hydrolysis of the formylation products to form water-soluble primary trimethine salts, and reaction of the water-soluble primary trimethine salts in the aqueous reaction mixture with acids of the formula (III): (H)n?X, in which: X has the same meaning as in formula (I) and n is a number from 1 to 3, or with water-soluble salts of such acids, in at least stoichometric proportions, and separation of the resulting trimethine salts of formula (I) which are only slightly soluble in water. Trimethine salts of formula (I) can be used as intermediates in the synthesis of heterocyclic compounds, particularly pyrimidines and pyridines.

摘要:An object of the present invention is to provide a method for producing a particulate water-absorbent polymer particle having remarkably improved long-term color stability, without an adverse effect (such as a delay in polymerization) on synthesis of the particulate water-absorbent polymer. The method includes the steps of polymerizing a monomer aqueous solution (B) containing (i) at least one type of monomer (A) that is capable of forming a particulate water-absorbent polymer by polymerization, (ii) at least one type of crosslinking agent, (iii) at least one type of polymerization initiator and (iv) an organophosphorus compound in an amount of not less than 1 but not more than 100 ppm by mass with respect to the monomer (A) so as to form a hydrogel polymer, and drying the hydrogel polymer. The method enables to provide an excellent particulate water-absorbent polymer that realizes (i) long-term color stability and improvement in urine tolerance and (ii) absorbing property, which are in such a trade-off relationship. In this way, the above object is attained.
