Stein pu r po s e o f t e s t : To demonstrate the feasibility of spray drying purchased choline chloride 70$ solution to achieve cost savings in the manufacture of Du Pont Basic Yellow BL, a potentially high volume yellow paper dye. d u r a t io n OF TEST: One charge. STANDARD INVOLVED: TMR-C-72-15 ' ANALYTICAL CONTROL: 0 No change Change described under Test Details TECHNICAL BASIS FOR CHANGE: OCNB 3001-79, 85; OCNB 2096-33 TEST DETAILS: See attachment. (Include Safety and Waste Disposal) Safety; There are no unusual hazards associated with this trial. The procedure has been reviewed with the Area and conforms to area safety practices. Hazards; Choline chloride (2-hydroxyethyl trimethyl ammonium chloride) is colorless as white crystals or white crystalline powder. It is hygroscopic and. is very soluble in water or alcohol. It is biologically active with the human body requiring 1.5 - 3.0 g. per day. A DISTRIBUTION: Nl J. E. Cole (3) Xr . Wiederhorn D. M. Dietz M. S. Moores B. ,R.

Dust Explosion Potential Dry material (200 mesh) did not detonate when tested in Azo Laboratory's spark box. The material did explode at Carneys Point (0.77 g./l. at 10 KU arc) but much less than the "Duponol" ME standard. The material was considered, safe and no additional testing was deemed necessary.

PSl/Sec '1800 Choline Chloride Powder 72 1420 515 Waste Disposal Dust Emission - A negligible amount of dry product is expected to be released to the atmosphere m the buixcSa-ng since xt is bt;xng xoadsd as a 70$ aqueous solution. Because of the extreme hygroscopicity of choline chloride, any dust passing through the Aerodyne separation after drying will be picked up by the water scrubber. Liquid Wastes - Minor amounts of choline chloride will be washed to the ditch during water clean-up of equipment. Test Details 1. With agitation on, charge the spray dryer feed tank with the weight of choline chloride 70$ solution specified by supervision. 2. Dry the solution under the following conditions: Drying air: Will be determined by slurry feed rate per normal operating procedure. Outlet air temperature: Start run at. 200P. and raise as necessary to 250P. t get product to less than 2$ moisture content. Steam pressure: Adjust as necessary to get desired slurry atomization conditions. DUP050467635 if TA-C-T2-415 Page 3 Choline chloride 70$ solution was satisfactorily dried at 572F. inlet and 257-268F. outlet temperature in a laboratory spray dryer. Product quality was satisfactory in that it was success fully converted to good quality (spectral and dyetest results) Du Pont Basic Yellow BL. The m. p. of choline chloride is ~'464-4720F. Since choline chloride is hygroscopic, it is necessary to dry to < 1.5 + .5$ moisture. The product is a free flowing solid at TThis moisture content. .3. Pack out the dry product in foil/polythene lined open head drums (FDF-303-9030) at 200 lbs. net. Add a bag-of CP-16 desiccant (137-925-1000) after filling to net weight and just before closing drum lid. label drums as Choline Chloride, Dry Lot "Desiccant Bag Inside" HYGROSCOPIC - DO NOT OPEN UNTIL READY TO USE 4. Collect sample by following standard sampling procedures for drying dyes. Hold 8 oz. sample for J. L. analysis. ltc DUP050467636
