These ranges were determined by laboratory runs and pilot plant demon strations. The effects of higher boiling Aroclor isomers on the fluidity of the product Increases as the temperature is reduced. However, low temperature viscosities (l.e. +20F) have been very consistent with pour point determinations. Furthermore, low temperature viscosities are more accurate, more reproducible and more meaning ful than absolute pour point determinations. Pour points were determined in regular ASTM tubes sus pended from a specially designed holder, which was mounted inside a frost free cold chest (Thermotron Corp.), equipped with accurate temperature controls. By means of an external rotating device, the tubes were rotated, through a 45 angle, from the vertical position to a horizontal position and the timing for the test was started. Flowing motions, on the surfaces of the constant temperature fluids, were observed through a frost-free sight glass. The lowest temperature, at which flow was observed within 5 seconds (ASTM), was desig nated as the pour point of the fluid. TOXICITY AND HAZARDS Aroclor is a liquid, under normal conditions, having a medium toxicity range for liquid ingestion and a high toxicity range for vapor Inhalation. The maximum allowable concen tration is 1 mg/cubic meter. ThiB material can cause derma titis, systemic poisoning from the fumes and yellow atrophy of the liver. There are skin, mucous membranes and eye irritation encountered in handling Aroclors. However, the crude Aroclor, used as the starting material in this process, is saturated with HC1. Hydrogen chloride is a gas and is very toxic. It is hazardous- to teeth, skin, eyes and mucous membranes. Aroclors offer no fire hazard. Aluminum chloride reacts with small amounts of water with such violence as to start a fire in the presence of organic .materials. Containers of this material should be stored completely enclosed or under a dry inert atmosphere. It reacts with moisture in the skin or mucous membranes to form a strong acid which can result in severe burns. Avoid inhaling the dust and wash affected areas with large amounts of water. Wear rubber gloves and goggles when handling this material. NEV 024992 738247 STLCOPCB4023669 8- - Calclum hydroxide is not dangerously toxic but is very hazardous to the eyes. It will burn the skin and the dust will affect the mucous membranes, in general, Attapulgus earth is not toxic. Persons handling large amounts of this absorbent should wear a respirator to avoid inhalation of the dust which contains silica. POLLUTION CONTROL The following weights of waste materials will have to be disposed of from the various process steps in the production of MCS 717. . Pounds of Waste Materials per 100# MCS 717 Process Steps Pounds Isomerization & Degassing Neutralization Distillation Attapulgus Earth Treatment Filter Cake 0.01# HC1 None 5# to 10# Residue 0.5# Attapulgus 1.0# Porocel 1.5# Residual HC1 contained in the original crude and the small amount of HC1, evolved during the isomerization, will be dissolved in a water scrubber and sewered. The still residue, including chlorination tars. Isomerization polymers, iron, aluminum and calcium salts along with highly chlorinated biphenyl, is transferred hot to a suitable container and sent to the toxic dump. The filter cake, from the Attapulgus Earth treatment, will go to the solid disposal interment. ' ms a/17/69 ' File Copy Approved by Manager of Research: J. D. Sullivan W. R.
