Abstract: CYCLODODECYLMETHYL CYCLODOECANECARBOXYLATE IS DISCLOSED AS A NOVEL COMPOSITION OF MATTER WHICH MAY BE NITROSATED WITH NITROSYLSULFURIC ACID TO LAURINLACTAM. THE LACTAM IS CONVERTED BY CONVENTIONAL METHODS INTO NYLON 12. NYLON 12 IS BECOMING AN INCREASINGLY IMPORTANT POLYMER COMPOSITION FOR THE MANUFACTURE OF MOLDED ARTICLES, FIBERS AND THE LIKE. THE PRESENT INVENTION RELATES TO A NOVEL ESTER COMPOSITION OF MATTER WHICH MAY BE EMPLOYED IN THE SYNTHESIS OF LAURINLACTAM WHICH IN TURN IS USED IN THE MANFACTURE OF NYLON 12. THE PRESENT INVENTION ALSO RELATES TO A METHOD FOR MANUFACTURING SUCH ESTER COMPOSITIONS.

Abstract: AN AMIDE IS PREPARED BY THE TRANSITION METAL-CATALYZED SELECTIVE HYDROLYSIS OF THE CORRESPONDING NITRILE IN A CARBOXYLIC ACID SOLVENT. THE CATALYST IS A CUPRIC, NICKELOUS, OR MERCURIC SALT, PREFERABLY A SALT IN WHICH THE ANION IS THE CONJUGATE BASE OF THE CARBOXYLIC ACID. ACCORDING TO A PREFERRED EMBODIMENT OF THE INVENTION, THE NITRILE IS AN AROMATIC NITRILE, E.G., TEREPHTHALONITRILE.

Abstract: A NORMALLY FAMMABLE ORGANIC POLYMER IS RENDERED FLAME RETARDANT BY THE INCORPORATION OF A COMPOUND CORRESPONDING TO THE FORMULA:

(2,2-DI(Q-),1,3,4,5-TETRA(X-)CYCLOPENT-4-EN-1,3-YLENE)2-Z

WHEREIN X IS CHLORO OR BROMO, Q IS HALO, HYDROGEN, OR A HYDROCARBYL OR HYDROCARBYLOXY GROUP, AND Z IS A TETRAVALENT SATURATED CYCLIC POLYBROMOHYDROCARBON GROUP CONTAINING 7-20 CARBON ATOMS AND 2-6 BROMINE ATOMS WHICH ARE PAIRED IN VICINAL POSITIONS. SUCH FLAME RETARDANTS INCLUDE, E.G., THE DIBROMINATED 2:1 DIELS-ALDER ADDUCT OF HEXACHLOROCYCLOPENTADIENE AND CYCLODODECATRIENE-1,5,9. IF DESIRED, THE FLAME RETARDANT MAY BE EMPLOYED IN CONJUCTION WITH A SYNERGIST, SUCH AS ANTIMONY TRIOXIDE.

Abstract: CYCLODODECANECARBOXYLIC ACID IS PRODUCED BY THE OXIDATION OF CYCLODODECANECARBOXALDEHYDE. UNSUALLY HIGH YIELD OF THE ACID IS OBTAINED IN HIGH PURITY BY CONDUCTING THE OXIDATION REACTION AT LOW TEMPERATURES IN THE PRESENCE OF A LOWER CARBOXYLIC ACID (E.G., ACETIC ACID) WITH OUT THE AID OF A CATALYST.

Abstract: POLYPROPYLENE IS RENDERED FLAME RETARDANT BY THE INCORPORATION OF N,N''-HEXANE-1,6-BIS(5,6-DIBROMONORBORNANE2,3-DICARBOXIMIDE). IF DESIRED, THE FLAME RETARDANCY MAY BE ENHANCED WITH SYNERGISTS, SUCH AS CERTAIN METAL COMPOUNDS (E.G, ANTIMONY TRIOXIDE) AND CERTAIN ORGANIC PHOSPHITES (E.G, DISTERAYL PENTAERYTHRITOL DIPHOSPHITE).
