The purification and characterization of chromatin from the posterior silk gland of two species of silkworm-Bombyx mori and phyldsamia. cynthia ricini-were described. These were taken from the worms on the fourth day of the fifth larval instar. The results showed that the chemical composition and ultraviolet spectra of chromatins thus obtained were similar to those of chromatins from higher eucaryotes.

The purification and characterization of chromatin from the posterior silk gland of two species of silkworm-Bombyx mori and phyldsamia. cynthia ricini-were described. These were taken from the worms on the fourth day of the fifth larval instar. The results showed that the chemical composition and ultraviolet spectra of chromatins thus obtained were similar to those of chromatins from higher eucaryotes. The electrophoretic patterns of chromatin proteins including histones from the two species of silkworm were compared. The chroma-tin isolated could stimulate the in vitro incorporation of isotopically labelled ATP when exogenous E. coli RNA polymearse was added. The relationship between the incorporation of labelled ATP and the DNA content of chromatin and the influence on incorporation in vitro of such factors as available energy regeneration systems, Mn++, rifamycin and others were studied. In vitro incorporation time curves for the two chromatins at 25℃ and 37℃ were compared.

A study of the regeneration process kinetics of AF-5 molecular sieve catalyst for ethylene-benzene alkylation showed that the rule of regeneration kinetics was different from that of the burning rate of coke which was generally considered as first order reaction with respect to the oxygen concentration. In this work, when the oxygen content is less than 1.2%, it was found that the coke burning rate was a zero order reaction with respect to the oxygen concentration and a second order reaction with...

A study of the regeneration process kinetics of AF-5 molecular sieve catalyst for ethylene-benzene alkylation showed that the rule of regeneration kinetics was different from that of the burning rate of coke which was generally considered as first order reaction with respect to the oxygen concentration. In this work, when the oxygen content is less than 1.2%, it was found that the coke burning rate was a zero order reaction with respect to the oxygen concentration and a second order reaction with respect to the coke concentration. A WRT-1 type micro-thermobalance was used in the determination and a kinetic equation of the burning rate of coke was induced. The equation is expressed in coke disappearing rate rA=k.CAa. As total deposit on catalyst contains both coke and bitumen, and the burning rate of bitumen is far quicker than coke.we can describe the regeneration process in reactor as a progressive change of zones, i. e. from heating zone to bitumen (high polymer) burning zone, coke burning zone, grey colored zone and zone of original color. This is the basis for the establishment of methematical model. By this model, under given burning time, inlet temperature of reactor and the highest allowable temperature for safe regeneration of catalyst, the corresponding oxygen content as well as quantity of regeneration gas could be calculated and thus the neccessary data for the design of regeneration system could be obtained.The determination of the burning rate of coke by thermoweight analysis provides accurate data neccessary for the establishment of kinetics pf burning coke and mathematical model. The method is simple, rapid and has good reproducibility.
