摘要:
The palladium complex disclosed herein is bis[tri(ortho-tolyl)phosphine] :palladium which is produced by reacting a palladium salt with tri(ortho-tolyl)phosphine and reducing the resultant bis[tri(ortho-tolyl)phosphine] palladium salt with an alcoholic alkali. This complex is useful as a catalyst for the production of 1,3-diene oligomers.

1,1-BIS(1'-METHYL-2'-VINYL-4',6'-HEPTADIENOXY)ALKANE IS OBTAINED BY ACETAL FORMATION OF 1-METHYL-2-VINYL-4,6-HEPTADIENOL WITH AN ALDEHYDE. The 1,1-bis(1'-methyl-2'-vinyl-4',6'-heptadienoxy) alkane is a novel curing compound.
摘要:
An air drying high solid coating composition containing 90% or more of solid components and consisting of (1) 95 - 50 parts by weight of low viscosity alkyd resin having an oil length of 60 or higher and a viscosity of Z.sub.4 or lower, (II) 5 - 50 parts by weight of 1,1-bis-(1'-methyl-2'-vinyl-4',6'-heptadienoxy)-alkane, and if necessary, (III) other components such as pigments, organic solvents and additives. The coating composition is quite effective in the prevention of air pollution and the saving of resources.
摘要:
High solid type alkyd resin compositions comprising 90 to 10 percent by weight of alkyd resin and 10 to 90 percent by weight of (1-methyl-2-vinyl)4,6-heptadienyl-3,8-nonadienoate and compositions prepared, if necessary, by adding bodying agents, driers and/or a small amount of thinner.

1,1-DI-(2,7 OCTADIENEOXYMETHYLENE)-1-(HYDROXYMETHYLENE)ALKANE PREPARED BY REACTING TRIMETHYLOL COMPOUNDS WITH BUTADIENE, USING A CATALYST CONSISTING OF PALLADIUM COMPOUNDS, ALKALI METAL SALTS OF WEAK ACIDS AND PHOSPHINES, SAID ALKANE BEING IMPORTANT AS A CHEMICAL INTERMEDIATE IN MANUFACTURING LUBRICATING OILS AND PAINTS.
摘要:
Reaction of (1-methyl-2-vinyl)4,6-heptadiene-1-ol with butadiene and carbon monoxide in the presence of a catalyst comprising palladium compounds and phosphine compounds provides a novel substance of (1-methyl-2-vinyl)4,6-heptadienyl-3,8-nonadienoate. This product can be made into a polymer at temperatures of 100.degree. to 250.degree. C.
