KEHQE Kettering Laboratory Cincinnati, Ohio Dear Dr. Kehoe: Attached is a copy of a letter from the Associ ated Ethyl Company Limited to our affiliates in England regarding your interest in the heavy ends in the bottoms from ethyl chloride manufacture. In accordance with this letter, ve are shipping to you today by Railway ^ ^ . 4 Express a one-liter sample of ethyl chloride bottoms pro duced in pilot plant operations here at Emeryville. Very truly yours, SHELL DEVELOPMENT COMPANY 1 HAC:ec Enel. 'THE ASSOCIATED ETHYL COMPANY LIMITED NORTHWICH, CHESHIRE Our Ref. MZF/4A Dr M. A. Matthews, The Shell Petroleum Company Ltd., Chemical Industry Management, St Helen's Court Great St Helen's LONDON E.C. 3. Date: 2.11.50 r' Dear Dr Matthews, Ethyl Chloride Process Recently we had a visit from Dr R. A. Kehoe who, as you probably know, is our organisation's Chief Medical Consultant. Dr Kehoe, of course, is aware of our general plans for increasing our "Ethyl" Fluid manufacturing ca pacity, and he mentioned to us a possibility that should be examined, that is the possible production in the ethyl chloride process of certain potentially dangerous polymers. I think, speaking very generally, that he was concerned essentially with aromatic materials possessing high boiling points of about 300C or over. From the data which you have so far made available to us, the bottoms would appear to have a composition essentially as follows: Ethyl Chloride Isopropyl Chloride 1.1 Dichloroethane 2 Chlorobutane 111 Trichloroethane 1.2 Dichloroethane Heavy Ends 9.9% 1.7% 63.0% 2.1% 5.5% 17.3% 0.5% 100.0% Also present are traces of 2 methyl-butene, 2 dichloromethane, allyl chloride, 1 chloropropane, t-butyl chloride, chloroform and carbon tetrachloride. The heavy ends from these bottoms then amount to about 5 -lbs per hour, which appears to be a relatively negligible order of magnitude.I I would, however, like to ask you if there is any information available on the composition of the 0.5% of. the heavy ends, from data which may be avail able from pilot plant operations. Furthermore, is it possible to give an opera tion on the probable performance of the full scale plant, in this respect. If by chance there should be any of these bottoms available in Emeryville I wonder if consideration could be given to letting Dr Kehoe have some of this material, in order that he might have it examined at the Kettering Laboratory in Cincinnati Yours very truly, hf/ecd (Sgd) H.
