  摘要：

  在二氧化碳存在下，硫胺素钠盐（III）与苯基乙二醛反应生成2-苯甲酰硫胺素（Va），后者在空气中易于氧化成硫胺素噻唑酮（VI）和苯甲酰酸。硫胺素盐酸盐（I）在三乙胺或氢氧化钠存在下与苯基乙二醛缩合也得到Va。该反应应用于多种α-酮醛，包括一些杂环乙二醛，生成了相应的2-草酰硫胺素衍生物（Vb-1），这些衍生物可转化为稳定的酰基衍生物（XIa-r）。

  Density and Water Exchange-Dependent Growth and Survival of Litopenaeus setiferus Postlarvae

  摘要：

  AbstractThis present study was designed to investigate the effects of stocking density and water exchange on the growth rate, survival and performance index of L. setiferus postlarvae under controlled laboratory conditions. The experiment was done with postlarvae (PL10 to PL40) at densities of 50, 150, 250 and 350 shrimp/m2 and various different water exchanges rate per day (0, 6, 12 and 18%). The maximum growth rate was obtained for shrimp with 12% water exchange per day at all densities. A reduction of the maximum growth rate was observed in relation to density with the highest values in shrimp stocked in a density of 50 and 150 shrimp/m2 (mean value of 0.53 mg/d) and the lowest in shrimp stocked in a density of 350 shrimp/m2 (0.24 mg/d). The multiple regression equation obtained to relate performance index (growth rate* survival : PI), shrimp density (X1) and water exchange (X2) was: PI = 0.31 + (0.001) X1+ 0.039 X2+ 2.28 × 10−6 X12+ (−0.0017) X22+ (0.000026)X1X2,R2= 0.78; P > 0.03. According to this equation the optimum shrimp density‐water exchange comhination was between 5 to 12% of water exchange at stocking density of between 50 and 150 shrimp/m2. Salinity, ammonia‐N and nitrite‐N increased according to the time spent in tanks without water exchange. With no (0%) water exchange, water quality parameters measured were outside the optimum for L. setiferus postlarvae. The use of optimum density and water exchange in a nursery system for L. setiferus with optimum variables established is proposed.

  An α-oxocarboxylate is manufactured by vapor-phase oxidation of α-oxoaldehyde and/or α-hydroxyaldehyde (which may have been formed by vapor-phase oxidation of 1,2-diol) with an alcohol or olefin using oxygen and a catalyst. This method provides an economical and effective route for α-oxocarboxylate manufacture from such inexpensive diols as ethylene glycol and propylene glycol.

  α -Oxoaldehydes are prepared by subjecting an alkylene glycol to the gas-phase reaction in the presence of an alcohol (a), oxygen and a catalyst (a) (first stage reaction). The aldehydes are further converted into α - oxocarboxylic esters by the gas-phase reaction thereof with an alcohol (b) or an olefin in the presence of oxygen and a catalyst (b) (second stage reaction). It is preferable that the alcohol (a) be the same as the alcohol (b). The processes can give α -Oxoaldehydes and α - oxocarboxylic esters in enhanced yields.
