Title: Production of glyoxylic acid
Inventor: MATSUNAGA YOSHINORI
IPC: C25B3/25
Filed: 1978-11-13
Abstract: PURPOSE: To improve the rate of utilization of oxalic acid by electrolytically reducing an aqueous oxalic acid solution through the use of a cation exchange membrane then subjecting the solution formed by reaction to ion exchange membrane method electrodialysis process to fractionate the same to the captioned product and unreacted aqueous oxalic acid solution and further making circulated use of the latter.  
     CONSTITUTION: After the aqueous oxalic acid solution whose concentration has been controlled with a control tank 1 is stored in a storage tank 3 by a pump 2, it is supplied to the cathode chamber of an electrolytic cell 5 having a cation exchange membrane 8. Next, the solution formed by reaction obtained through electrolytic reaction is sent into a desalting chamber solution tank 11, where it is added with hydrochloric acid or the like and the control of the desalting chamber solution is accomplished. Next, this desalting chamber solution is sent to an ion exchange membrane method electrodialysis cell 14 and the unreacted oxalic acid is dialized into a concentrated chamber solution through the ion exchange membrane, after which it is sent into a tank 16. Part thereof is circulated to the dialysis cell 14 and the rest is returned to the control tank 1 and is reused. On the other hand, the solution containing glyoxylic acid is circulated to the tank 11 if necessary and the solution of less oxalic acid contents is recovered through takeout part 20.

Title: Reduction of aromatic nitrile
Inventor: MINATO ICHIROU
IPC: C07B61/00
Filed: 1979-10-26
Abstract: PURPOSE: To prepare an aromatic primary amine, in high yield, by the catalytic reduction of the corresponding aromatic nitrile under specific conditions.  
     CONSTITUTION: An aromatic nitrile (e.g. benzonitrile) is subjected to the catalytic reduction with Pd catalyst in the presence of CO 2  to obtain the corresponding primary amine (e.g. benzylamine). The reaction is carried out in a low-cost aqueous solvent without using a strong acid or strong alkali, and the corrosion of the reaction vessel can be prevented. Since the yield of the primary amine is high, its purification is easy. The absence of NH 3 , etc. in the reaction system facilitates the treatment of waste gas.
