摘要:
Lactam-blocked products of alicyclic isocyanates are obtained by blocking an aromatic isocyanate with lactam and subjecting the resulting blocked product to catalytic hydrogenation with use of a Rh catalyst.The blocked alicyclic isocyanate obtained thus can be used, for example, as a curing agent for synthetic resins such as epoxy resins or as a starting material of urethane coatings.The blocked isocyanate, if desired, may be subject to distillation whereby an alicyclic isocyanate is isolated by thermal dissociation and separation of the blocking agent.
摘要:
A parallel plane holding mechanism is constructed as follows. Beams are provided on the peripheral portion of a flat plate-shaped weight member. A base plate is provided so as to face the weight member. First and second electrodes are provided on both surfaces of the weight member and the base plate to face each other. A voltage is applied between the first electrode and the second electrode so that the distance between the weight member and the base plate is controlled to move the weight member to thereby hold a reference surface of the weight member to be parallel to a predetermined reference surface.
