Based on proposed increases in the demand for products made from 1, 4-diamino-2,3-dichloroanth.raquinone consumption of SO2CI2 could be about 1MM pounds in 1971. One million pounds of SO2CI2 involves the handling of almost 1,400 drums. This drum handling is not only inefficient but creates a significant drum disposal problem. Approximately 700 of the drums handled are handled as part drums increasing the opportunity for incidents due to mis-identification. The economics of using bulk SO2CI2 appear attractive. B. A. Bell quotes about $12.50 per one hundred pounds as opposed to the current $14.20 per one hundred pounds. Myron Fidyk's work indicates labor saving incentives for going to bulk SO2CI2. Safety, efficiency,, and economics indicate that at today's con sumption levels bulk handling of S02C12 is worth consideration.

L0 Eiehardson, Admini Co Bo Livingston, "Freon MATOFACTOBB OF HULF0BYL CHLOBID ^^ ___ In response to your request, we have examined the possibility of manufacturing SC_Clp on Chambers Works, It is our understanding that this request stemmed from the recent inability of Hooker (only TJ.S. supplier of SO^Clg) to meet our increased needs (100M pounds per month versus 4pK pounds per month forecast). Conversa tion. with S, A, Peddrick reveals that he is quite optimistic that Hooker will, be able to meet our requirements by September, Production at Chambers Works would not be a difficult -undertaking although suitable equipment would have to be procured and installed. The process is very simple, consisting of passing S0_ and Clp through cooled inconel tubes packed with charcoal, fol lowed d j collection of the condensed product (Ref,, I, 2, 3), Purification is not necessary if the process shown on the attached sketch is used. However, this route would take both time and money to implement and, frankly, does not appear attractive for quick short-term relief. Much more attractive, should the need persist into September, would be to take advantage of Beaumont11 s SO^Clg capability. Their facility is integrated with "Hypalon" manufacture and is presently- running at capacity. After September 15a however, their schedule falls to five day per week operation. According to E, P. Madrulli, they could, then raake our 1C0M per -month SOpCl^ requirements on weekends, Ho further work will be done on this project unless specificallyrequested.

CHLORIDE WITH DIETHYL ETHER A Station chemist sent the following article to us from, the January, 1966, issue of "Chemistry & Industry" which may he of interest to others here at the Station. "Recently we attempted to prepare di-isopropyl sulphate following a method (Medvedev and Alexejave, Ber. dt. chem. Ges., 1921, 65B, 132) which involved treating sodium isopropoxide with sulphuryl chloride in diethyl ether. Shortly after the sulphuryl chloride was dissolved in ether, a vigorous, exothermic reaction occurred. Large volumes of hydrogen chloride gas and ether vapour were evolved. Reaction was almost instantaneous in the presence of a trace of hydrogen peroxide or when old stocks of ether were used. Gas chromatographic analysis and fractional distillation of the product obtained by performing the re action under controlled conditions showed that chlorinated derivatives of diethyl ether, including 1,2-diehloroethyl ethyl ether were formed. These observations suggest that care should be exercised in the use of sulphuryl chloride in ether as a reagent. The solution is potentially hazardous and side-reactions in volving chlorination of the solvent may reduce the yields of desired products."
