摘要： 1310621 Syndiotactic 1,2-polybutadiene UBE INDUSTRIES Ltd 1 Dec 1970 [2 Dec 1969 (2)] 57056/70 Heading C3P Butadiene is polymerized to 1,2-polybutadiene in the liquid monomer or in an inert liquid diluent by using a catalyst comprising (a) a cobalt compound, (b) an organoaluminium compound, AlR 3 , where R is a C 1 -C 6 hydrocarbon group, (c) carbon disulphide and optionally (d) a nitrile R 1 (CN) n where n is 1 or 2 and R 1 is a mono- or di-valent aliphatic, araliphatic or aromatic hydrocarbon group. When only components (a), (b) and (c) are used a novel polymer is obtained having a linear, highly syndiotactic structure, a melting point of at least 200‹ C. and good solvent resistance. Addition of component (d) in varying amounts enables polymers to be produced with a selected melting point in the range 100-210‹ C. The catalyst components are preferably mixed in the presence of the butadiene. The cobalt compound should preferably be soluble in the reaction medium, e.g. with benzene as the diluent, cobalt octoate, naphthenate or acetylacetonate or CoCl 2 complexes, such as the pyridine complex. As component (b), Et 3 Al is exemplified and as component (d), acetonitrile, benzonitrile, adiponitrile, sebaconitrile or benzyl cyanide.

摘要： PURPOSE:To purify p-vanillin in high yields useful as a fixative, modifier, and blender of a spice, by adding a specific ratio of water to crude p-vanillin having a small amount of a methylvanillin, followed by extraction at a specified temperature. CONSTITUTION:14-30pts.wt. of water is added to one part by wt. of crude p- vanillin having not more than 1.3wt% of a methyl vanillin and p-vanilin is extracted with the water layerat 40-60 deg.C. EFFECT:A trace amount of a methylvanillin, which can not be removed by an ordinary distillation, is eliminated to give a high-purity p-vanillin.
