This paper investigates the reaction between pool chlorinators and gasoline. In particular, the propensity for self-ignition and the resulting chemical products were studied. An organic pool chlorinator was combined with gasoline in varying proportions in an attempt to form a hypergolic mixture. None of the combinations resulted in self-ignition, but larger quantities of chlorinator produced vigorous light-colored smoke and a solid mass containing isocyanuric acid and copper chloride. Additionally, the chlorinating abilities of different commercially available pool chlorinators were explored. When Ca(ClO)(2) and sodium dichloro-s-triazinetrione-based chlorinators were used, the presence of gasoline was still visible after 10 days, despite limited chlorination. The trichloro-s-triazinetrione-based chlorinator, however, caused efficient chlorination of the C(2)- and C(3)-alkylbenzenes, making gasoline no longer identifiable. 相似文献

The lecture traces the process of commercialisation in English law from its early stages to the present day. Until the mid-eighteenth century the law was in a process of integration , overcoming a judicial preoccupation with technicalities and procedures to form a body of rules which merchants could trust. From that point on the law has assumed a proactive role as an engine for trade. The nineteenth century is marked by legal facilitation , where new institutions were fashioned as a robust commercial framework for the Industrial Revolution. From the end of that century to the present day business law has served to regulate , building a sensitive framework for commercial development that balances the needs of commerce with the needs of society as a whole. 相似文献

What has happened to British Labour Law over the past 40 years?It has become a larger more juridified subject. But its developmentrequires an understanding of the New Capitalism that has emerged,with capital more mobile and powerful in globalisation. Threeaspects are chosen for comment: First the meaning of the recentreview by the Law Lords of economic torts. Second, the argumentsabout the contract of employment in Britain and Italy, in thecontext of the regulation debate, forthcoming legislation andthe search for acceptable standards of social justice. Thirdly,the scene is set in European law for a new chapter in the tensionbetween employers' economic freedoms in the internal marketand social rights, including the right to strike. 相似文献
