The present paper attempts at a discussion of the catalytic effect of a new catalyst on the combstion of double-base propellant, establishing itself on the combustion theory based upon molecular catalysis. In the process of reaction of the catalyst, the metal (lead) contained in it is introduced in a molecular state into the substance catalyzed (nitro-cellulose). As a result, a new component called nitrocellulose lead, a form of metallic polymer is thus formed. The formation of this new component...

The present paper attempts at a discussion of the catalytic effect of a new catalyst on the combstion of double-base propellant, establishing itself on the combustion theory based upon molecular catalysis. In the process of reaction of the catalyst, the metal (lead) contained in it is introduced in a molecular state into the substance catalyzed (nitro-cellulose). As a result, a new component called nitrocellulose lead, a form of metallic polymer is thus formed. The formation of this new component in doable-base propel lants may not only help to overcome some difficulties caused in the technological process of propel-lant manufacture due to the use of inorganic and organic lead salts, but may also improve homogeneity of the propel lant components and stability of combustion. Results obtained from the experiments show that in the case of 5 and 7% nitrocellulose - lead introduced into the double-base propellant, plateau characteristic appears on the u(p) curve within the range of 40-100 atm, with the pressure exponent of 0.24. This is the range of pressure appl id in most solid propellant engines.

本文基于分子催化燃烧理论的设想,研究了一种新催化剂对双基药燃烧的催化作用。这种新催化剂是将起催化作用的金属(铅)以分子状态引进到被催化的物质(硝化棉)之中——硝棉铅,它是金属高聚物的一种。在双基药中使用硝棉铅可以克服使用无机或有机的铅盐而导致制造火药工艺中的困难和成分的不均一性及燃烧的不稳定性。本实验得出结果:双基药中加入5和7%硝棉铅,在40~100大气压区间出现接近平台的u(P)曲线,其压力指数为0.24。此压力范围正是大多数固体燃料发动机所使用的。

Based on the pseudophase model of micellar catalysis and some assumptions,the kinetic equations of mixed micellar catalysis have been drived in the case where reactant concentrations are higher than micellar concentrations in this paper.The alkaline hydrolysis of dimethylformamide(DMF) has been studied at 40℃ in the mixed micellar solutions (CTAB Brij35,SDS Brij35,CTAB Im,SDS Im,Brij35 Im) and in the solutions of functional molecule (1 benzyl 2 hydroxymethyl imidazole)(Im) with analog thermogram method of thermokinetics.The kinetic parameter k m in micellar pseudophase and the association constant of reactant with micelle K 1 ,and the kinetic parameter of functional molecular catalysis k f and the association constant of reactant with functional molecules K have been calculated with these kinetic equations,respectively.Alkaline hydrolysis of DMF is catalyzed by all researched mixed micelles and functional molecule.The authors suppose the micropolarity and local concentration effect of mixed micelles (CTAB Brij35,SDS Brij35) can account for the mixed micellar catalysis,mixed micelles which are consisted of Im with surfactants are somewhat like α chymotrypsin.
