Soc. The ethyl zinc halide can be ethyl zinc chloride, ethyl zinc bromide, ethyl zinc iodide or a mixture of two or more of such ethyl zinc halides.4. 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 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 zinc and ethyl halide can be used in equimolecular amounts, although it has been found preferable to employ an excess up to 100% of the zinc.Example 1 In a rection vessel equipped with reflux condenser 100 parts of a finely ground zinc-copper alloy containing 6% by weight of copper (the alloy containing 1.44 mols of zinc) were reacted, while being stirred, with 50 parts of ethyl iodide and 35 parts of ethyl bromide at a temperature of about 50 C. After the reaction had started a solution of 28 parts of ethyl iodide and 20 parts of ethyl bromide in 100 parts of cyclohexane was gradually added over one hour. A process according to claim 1 wherein the ethyl zinc halide is ethyl zinc bromide.United tates Patent 2,996,529 PREPARATION OF DIETHYL ALUMINUM CHLORIDE Harmannus Bos, Geleen, Netherlands, assignor to Stamicarbon N.V., Heerlen, Netherlands I No Drawing.

In addition, we employ it as a reagent for the scission of certain kinds of C-O and N-O bonds. The preparation of alkyl halides can be carried out by nucleophilic substitution reaction of alcohols from alkanes. Also, its forms by the reaction between aluminum and iodine. 15H 2 O, may be prepared by the reaction of hydroiodic acid, HI, with aluminum or aluminum hydroxide. 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. 628,959 "Claims priority, application Netherlands Dec. 21, 1955 Claims. No. 7Unless otherwise stated in the specification and claims, all parts and percentages are by weight.The reaction of the aluminum trichloride with the ethyl Zinc halide, e.g., ethyl zinc bromide, can be represented by means of the equation:Instead of pure zinc, there can be employed an alloy of zinc containing a small amount, e.g., 1 to by weight of another metal or metals, such as copper or sodium. Components of aryl ethers are removed and the aluminum ions and iodide ions take the … The ethyl zinc halide formed by this reaction is poorly soluble in the liquid.3. 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. 61 to 64, 784 and 785.During the reaction, further amounts of ethyl halide can be added. Moreover, it cleaves aryl ethers and deoxygenates epoxides.It is an ionic compound that is used as a catalyst (added to make the process faster) in certain organic reactions and as a spray when treating animal stalls. 26, 1956 OTHER REFERENCES Krause and von Grosse: Die Chemie der metall-organischen V'erbindung (Berlin 1937), pp. If you have trouble signing in to your PrepChem Account or encounter difficulties during registration, please contact us directly info@prepchem.cominfo@prepchem.com In organic chemistry sometimes it acts as a catalyst that fastens the reaction between elements or compounds. 260-448) The present invention relates to the preparation of diethyl aluminum chloride.It has now been found that the objects of the present invention can be attained and diethyl alumium chloride can be obtained in excellent yields by distributing aluminum trichloride in a suspension containing an ethyl zinc halide and resulting from a reaction between zinc and an ethyl halide in the presence of an inert organic liquid and subsequently heating this mixture to 60 to 250 C. and distilling the diethyl aluminum chloride formed from the reaction mixture.It is known that when aluminum is dissolved in ethyl chloride, a mixture of ethyl aluminum dichloride and diethyl aluminum chloride is formed.
