An enzymatic method for optical resolution of DL-arginine by immobilized cell was developed,and many factors affecting the resolution were studied.

D-arginine and L-citrulline were produced by means of biotransformation of DL-arginine in the presence of arginine deiminase which was found in the Streptococcus faecalis.

Synthesis of N-ferrocenylformyl-DL-alanine;

Kinetics of Mycelium-immobilized Packed Bed Continuous Resolution of DL-alanine;

N-Phenylacetyl-DL-alanine(Ⅰ) was formed by reacting DL-alanine and phenylacetyl choloride in molar ratio 1.

Chromatographic resolutions of DL-amino acids were achieved on the chiral stationary phases by using 0.

Surface Recognition of the Space Group and Chiral Array on DL-valine Crystalline Structure Observed by AFM;

2-Phenyl-1-chloro-1-trichloroacetylcyclopropane (3) was obtained from the reaction of styrene with carbene generated by refluxing the mixture of DL-valine and hexachloroacetone in chlorobenzene un-der an atmosphere of nitrogen.

Firstly, DL-glutamine was synthesized from DL-glutamic acid on larger scale.

The experiment results indicated that a higher yield of DL-glutamic acid(DL-Glu) could be obtained when the molar ratio of salicylaldehyde to glutamic acid was 0.
