ARSAKILIC ACID STARTUP FACT SHEET

• ' 1 . What Is Being Produced? The major portion of the equipment is devoted to the manufacture of crude arsanilic acid (TA) . The crude product ie then coverted into Carbarsone or purified arsanilic acid (AA-100).

2. Raw Materials Aniline (AN) A colorless oily liquid - virtually insoluble in vater. Arsenic Acid A colorless dense liquid. Perchloroethylene (PCE) A clear water-white liquid commonly used for dry- cleaning - insoluble in water. Caustic (25%) A strongly alkaline liquid. Hydrochloric Acid (HC1) A strongly acidic liquid, .— water-white. Nuchar SN „ .. j '....» A black powder used to purify* and decolorize. Solka Floe and Piasbestos Powdery solids used as filter aids.

3. Special nomenclature and Abbreviations • AA - Arsanilic Acid TA - Crude AA (Technical Arsanilic Acid) AN - Aniline PCE - Perchloroethylene AW - Aniline Vater (vater with 2% aniline) ML - Mother Liquors - the liquid recovered from a filtration.

ARSANILIC ACID STARTUP FACT SHEET (CONT'D) • f 4. Process Operations Reaction - chemical combining of two or more compounds to form a new compound or compounds. Extraction- the separation of two miscible liquids by the use of a solvent which preferentially dissolves one of them. Hydrolysis- a reaction with water ("hydro"). Stripping - the separation of a component from a mixture by boiling it away with the help of another solvent. Filtration- removal of a solid from a slurry (liquid and solid mix). (Centri- fugation) Crystallization - formation of a slurry (solid) by cooling a saturated solution. Concentration - reduction in the volume of a solution by evaporation of some of the excess solvent. Distillation - the separation of compounds by utilization of the difference £n boiling points (volatility).
