    摘要: A process for producing a high yield of N-carbobenzoxy-L-aspartic anhydride from N-carbobenzoxy-L-aspartic acid in a very short period using commercially acceptable reaction conditions is disclosed. The process is characterized by reacting N-carbobenzoxy-L-aspartic acid with acetic anhydride in the presence of a metal oxide, a metal hydroxide, a metal salt of acid, an organobasic compound or an acid having a dissociation constant of 5.times.10.sup.-2 or more.

    摘要: The reaction between L-aspartic acid and benzyloxycarbonyl chloride is carried out at a specific pH range, i.e., 12.0 to 13.5, whereby highly pure N-benzyloxycarbonyl-L-aspartic acid can be obtained in high yields, while both the by-production of N-benzyloxycarbonyl-.alpha.- or .beta.-L-aspartyl-L-aspartic acid and the decomposition of benzyloxycarbonyl chloride to benzyl alcohol are suppressed.

    摘要: A measuring cylinder into which liquid is supplied is provided with pressure transmitters for sensing the liquid pressure corresponding to the amount thereof. The pressure transmitters are connected with a pressure transformer to transform the pressure into an electric signal for controlling valves to stop and start the supply of liquid into the cylinder. The pressure transmitters are located in the cylinder at different levels and switched to be selectively operated in combination with the pressure transformer. In a preferred embodiment of the invention, the shape of the cylinder is designed so that the diameter thereof increases discretely from the lower part to the upper part thereof. One of the pressure transmitters is located at the bottom of the cylinder and the others are located at levels substantially the same as those at which the diameter of the cylinder increases.
