Reaction ended, filtering product, steamed in a water bath to the surplus of carbon disulfide, and then concentrated solution, cold cut crystal with hexane washing, drying at 100 ° C, a system of anhydrous. A process according to claim 1 wherein the ethyl zinc halide is a mixture of ethyl zinc bromide and ethyl zinc iodide.After the crude product separated out by distillation was redistilled at 113 C., and a pressure of 26 mm. Aluminium iodide, AlI 3, may be prepared by heating aluminium with iodine in a sealed tube, by passing iodine vapour over heated aluminium, or by adding aluminium to iodine dissolved in carbon disulphide. Aluminum Iodide Preparation Iodine belongs to the halogen family which is highly reactive non-metals . A process according to claim 3 wherein the temperature of heating is 60-25 0 C.. 4 References Cited in the file of this patent UNITED STATES PATENTS 2,786,860 Ziegler et al Mar. The ethyl halide can be dissolved in the inert liquid. This process of preparing diethyl aluminum chloride has the disadvantage that valuable triethyl aluminum must be used as a starting material.Sidgwick: Chemical Elements and Their Compounds, vol. The preferred ethyl halide is ethyl bromide (see I ob and Reich: Bul. 628,959 "Claims priority, application Netherlands Dec. 21, 1955 Claims. A great example of this is the reaction of aluminum and iodine. mercury, 49 parts of diethyl aluminum chloride were obtained (a yield of 91% based on the aluminum trichloride).Subsequently, 60 parts of aluminum trichloride (0.44 mol) suspended in 100 parts of cyclohexane, were added over 30 minutes and the reaction mixture was boiled for one more hour.In order to obtain the suspension containing ethyl zinc halide, finely divided zinc is reacted with an ethyl halide, e.g., ethyl chloride, ethyl bromide or ethyl iodide. Preferably, 30 to 60 parts of solvent are employed per parts of the total reaction mixture including the aluminum trichloride. Purple vapor forms when iodine reacts with aluminum in the presence of water.Commonly we use it as an animal stall cleaner where its vapor works. In organic chemistry sometimes it acts as a catalyst that fastens the reaction between elements or compounds. It separates from carbon disulphide in colourless crystals of density 2.63, melts at 125°, and boils at 350°; its critical temperature is 955°. When a mixture of ethyl bromide and ethyl iodide is employed, they are generally used in an amount of 0.1 mol to 1 mol of ethyl iodide for each mol of ethyl bromide. A process according to claim 1 wherein the temperature of heating is 60250 C.2.
