  Study of the tensile fracture of plates with a rigid linear inclusion

  摘要：

  The limit equilibrium of elastoplastic body is studied under the conditions of a plane problem. The body contains a linear inclusion, which is rigid but of finite rupture strength. The plastic or prefracture zones develop near the ends of the inclusion and are modeled by slip cracks along the matrix-inclusion interface. A new interpretation of the boundary conditions is proposed to solve a model problem for such a composition, and its analytical solution is derived. Two possible mechanisms of local fracture are considered: (a) fracture of the inclusion and (b) separation of the inclusion. The critical length of the inclusion is determined. This length together with the elastic and strength parameters of the composition determines the mechanism of local fracture. The limit loads are found for each mechanism of fracture.

  A process for the production of 2,3,5-trimethyl- benzoquinone (TMBQ) from 2,3,6- trimethylphenol (TMP) is described, comprising contacting TMP with molecular oxygen in a medium of water and an aliphatic alcohol having from 4 to 10 carbon atoms in the presence as a catalyst of a copper halogeno complex represented by the general formula as shown below or a mixture of the copper halogeno complex and an alkali metal halide. wherein M is an alkali metal or ammonium, Cu(II) is a divalent copper, X is a halogen atom, I is an integer of 1 to 3, m is 1 or 2, n is an integer of 3 to 8, p is 1 or 2, and II + 2mp = np. The present process yields various advantages; for example, TMBQ can be produced with high selectivity, and since the reaction is performed in a specific medium (the medium is heterogeneous because the alcohols are immiscible or little miscible with water) and TMBQ is soluble in the alcohol layer, while the catalyst is soluble in the water layer, TMBQ can be easily separated and reuse of the catalyst can be accomplished by a simplified procedure. TMBQ is a useful compound as an intermediate for use in the preparation of Vitamin E.

  本发明描述了一种从 2，3，6- 三甲基苯酚（TMP）生产 2，3，5- 三甲基苯醌 （TMBQ）的工艺，该工艺包括在水和具有 4 至 10 个碳原子的脂肪醇的介质中，在卤化铜络合物 （通式如下所示）或卤化铜络合物与碱金属卤化物的混合物作为催化剂存在的情况下，使 TMP 与分子氧接触。 其中 M 为碱金属或铵，Cu(II) 为二价铜，X 为卤素原子，I 为 1 至 3 的整数，m 为 1 或 2，n 为 3 至 8 的整数，p 为 1 或 2，II + 2mp = np。本工艺具有多种优点，例如，可以高选择性地生产 TMBQ，而且由于反应是在特定的介质中进行的（该介质是异质的，因为醇类与水不相溶或几乎不相溶），TMBQ 溶于醇层，而催化剂溶于水层，因此 TMBQ 可以很容易地分离出来，催化剂的重复使用也可以通过简化程序来完成。TMBQ 是一种有用的化合物，可用作制备维生素 E 的中间体。
