    摘要: 3,4-Diacetoxybutene-1 can be easily isomerized into 1,4-diacetoxybutene-2 by contacting it with a cation exchange resin. This method is capable of providing an excellent reaction result and is free of the problem of corrosion of apparatus as well as the problem of formation of by-products. When acetic acid is present in said isomerization operation, the reaction rate is increased. Further, combination of this isomerization method with separation of 1,4-diacetoxybutene-2 from 3,4-diacetoxybutene-1 by distillation enables production of high-purity 1,4-diacetoxybutene-2 at a high efficiency.

    摘要: Unsaturated diesters are produced by a process which comprises reacting, in a flowing gaseous phase, a gaseous mixture comprising a conjugated diene, a carboxylic acid and molecular oxygen in the presence of (A) a catalyst comprising palladium, vanadium, antimony and at least one alkali metal carboxylate, or in the presence of (B) a catalyst comprising palladium, vandium, antimony, at least one alkali metal carboxylate and at least one alkali metal halide. The catalyst (A) maintains a high activity and a high selectivity for a long time. The catalyst (B), in which further the alkali metal halide is added, shows a higher activity and a higher selectivity for a longer time. And its activity and selectivity are stable and durable at high temperatures such as 160.degree. - 200.degree. C. Furthermore, the addition of the alkali metal halide suppresses combustion reaction of dienes such as butadiene remarkably. Additionally, the catalysts (A) and (B), especially (B) can be easily reactivated when they lose activity.

    摘要: In a process for preparing diacetoxybutene by subjecting butadiene, acetic acid and oxygen to reaction, the discharge gas from the reaction system or purification system, containing butadiene and/or acetic acid, is treated by contacting with diacetoxybutene and/or diacetoxybutane (absorbent) to allow butadiene and/or acetic acid to be absorbed by said absorbent. A part of the diacetoxybutene separated in a distillation tower from the reaction product solution containing diacetoxybutene produced by said three-component reaction can be used as said absorbent. In this case, butadiene and/or acetic acid can be recovered from said discharge gas by supplying the absorption solution into said distillation tower. Also usable as said absorbent is diacetoxybutane obtained by hydrogenation of diacetoxybutene. In this case, it is possible to recover butadiene and/or acetic acid by supplying the obtained absorption solution into said distillation tower and further transferring the obtained mixture of diacetoxybutene and diacetoxybutane to the hydrogenation step without separation. In said process for preparing diacetoxybutene, the substantial portion of the discharge gas from the reaction system may be circulated back to the reaction system for reuse, and the remaining discharge gas may be supplied into an absorption tower.

    摘要: The external base electrode has a two-layered structure where a p-type polysilicon film doped with a medium concentration of boron is laminated on a p-type polysilicon film doped with a high concentration of boron. Therefore, since the p-type polysilicon film doped with a high concentration of boron is in contact with an intrinsic base layer at a junction portion between the external base electrode and the intrinsic base layer, the resistance of the junction portion can be reduced. In addition, since the resistance of the external base electrode becomes a parallel resistance of the two layers of the p-type polysilicon films, the resistance of the p-type polysilicon film whose boron concentration is relatively lower is dominant.
