Emerency Sevices Managment - Advaced Interactions of Hazardous Case Study
Emerency Sevices Managment - Advaced Interactions of Hazardous Materials IV - Case Study Example T2 laboratory was a manufacturer of methylcyclopentadienyl manganese tricarbonyl (MCMT). MCMT being a toxic and a highly inflammable liquid, it is classified as extremely hazardous substance (EHS) (United States & Chemical Safety and Hazard Investigation Board, 2009). A chemical recipe serves as a guide during the manufacturing process. Metalation is the first step where metallic sodium that was previously melted is reacted with methylcyclopentadiene (MCPD). This reaction occurs in the presence of diglyme (diethylene glycol dimethyl ether). Heat is applied before the reaction can occur, and this may be necessary to enable overcome the activation energy required for initiation of the reaction. Besides, the heating converted sodium to its molten form increasing the surface area and reduced the MCPD dimer into two molecules. These two changes are necessary for the reaction to occur. Two products are obtained from this reaction; hydrogen gas and sodium methylcyclopentadiene. The hydrogen gas produced is released into the atmosphere. Substitution is the second step during which dry powder of manganese chloride was added and reacted with sodium methylcyclopentadiene forming sodium chloride and manganese dimethylcyclopentadiene. The final step involves the addition of carbon monoxide, a process called carbonylation. It leads to loss of one methylcyclopentadiene, and its place is replaced by three CO molecules forming the famous methylcyclopentadienyl manganese tricarbonyl. Through the distillation of the mixed final product, you obtain clean methylcyclopentadienyl manganese tricarbonyl. During metalation energy was being lost in the form of heat, cooling was necessary for the reaction to proceed regularly. The rate of reaction also increases with the rise in temperature. It is evident that a 100C increase in temperature causes a two-fold increase in the rate of
