标 题 :Synthesis of high vinyl polybutadiene utilizing a molybdenum catalyst system
发明人：CASTNER KENNETH F; BELL ANTHONY J; GLENN KIMBERLY M
权利人:GOODYEAR TIRE & RUBBER
摘要:High vinyl polybutadiene rubber is utilized in a variety of applications. For instance, high vinyl polybutadiene is utilized in tire tread rubber compositions because it provides both good traction and rolling resistance. The present invention discloses a technique for synthesizing high vinyl polybutadiene utilizing a molybdenum catalyst system. This molybdenum catalyst system can be utilized in aliphatic solvents with high yields of about 75% being attained. The molybdenum catalyst systems of this invention are comprised of (a) a molybdenum containing compound which is prepared by modifying molybdenum pentachloride, molybdenum trichloride, or molybdenum tetrachloride with an alkyl carboxylic acid or an aryl carboxylic; and (b) an aluminum containing compound which is prepared by modifying a trialkyl aluminum compound with a phenol. The molecular weight of the high vinyl polybutadiene being prepared can be reduced by modifying the trialkyl aluminum compound with an allylphenol, such as 2-allylphenol.

标 题:Process for the preparation of a 2-alkylphenol
发明人：STEINMETZ ARTHUR
权利人:RIEDEL DE HAEN AG
摘要:A 2-alkylphenol is prepared by reduction of a 2-acylphenol in the presence of a metallic catalyst. The reaction is carried out at a temperature of 80° to 200° C. and under a pressure of 10 to 100 bars, and a base metal, in particular copper, is used as a catalyst. It is particularly advantageous to use the catalyst in combination with a support. The hydrogenation of the acylphenol is advantageously carried out in the presence of an inert solvent. The process can be carried out continuously or discontinuously. The alkylphenols obtained are suitable for use in the synthesis of active substances having biocidal properties.

标 题:Process for phenol alkylthiolation and its application to the synthesis of 4-acyl-2-alkylthiophenols
发明人：VOTTERO CATHERINE; LABAT YVES; POIRIER JEAN-MARIE
权利人:ELF AQUITAINE
摘要:The invention relates to the preparation of alkylthiophenols by reaction of a dialkyl disulphide with a phenol. n In the process according to the invention, the reaction is carried out in the presence of aluminum chloride or of ferric chloride in a solvent of the alkylbenzene type or, soley in the case of methylthiolation, in an excess of dimethyl disulphide. n This process makes it possible, in particular to obtain, with a selectivity and in a yield which are excellent, 2-alkylthiophenols which may then be converted into 4-acyl-2-alkylthiophenols by means of a reaction at a temperature ranging from 40° to 100° C. with a complex BF 3 :2RCOOH where R denotes an alkyl or propenyl radical, in a proportion of 10 to 15 moles of complex per mole of 2-alkylthiophenol.
