French spray-drying

HYDROXY-/W-XYLENE (105-67-9) CjHioO (CH3)2C6HjOH Combustible solid (flash point>233°F/>l 12°C Fire Rating 1). Dust forms explosive mixture with air. A weak organic acid. Reacts violently with strong oxidizers. Incompatible with acid chlorides acid anhydrides sulfuric acid, caustics, ammonia, aliphatic amines, alkanolamines, isocyanates, alkylene oxides, epichlorohydrin. Corrodes metals in the presence of moisture, including steel, brass, copper and its alloys. On small fires, use water spray, dry chemical powder, alcohol-resistant foam, or COj extinguishers. HYDRURE de CALCIUM (French) (7789-78-8) see calcium hydride. 

The relative mildew growth on polymer and on paint samples exposed to Aurobasldlum pullulans was also studied using the "Zabel Test." In this procedure, veneer strips of southern yellow pine and bass wood are sterilized, cooled, and painted (2 coats with 24 hrs. drying time). After 2-3 days the strips were soaked In distilled water, sterilized at 100 C and placed vertically In 16-ounce French square bottles containing 20 gm. of vermiculite. A mlcronutrlent enriched nutrient media was then poured Into the vermiculite (100 ml per bottle). After sterilization at 121 the painted strips were positioned so that the bottom of the painted zone was 0.5 cm above the vermiculite surface. The specimens were Inoculated with a spore suspension of Aureobasldlum pullulans (16624) by pipette. Incubated two months at 28 , and then rated visually with a 20x binocular. In the weathered series, the specimens were exposed four days In an Atlas Weather 0 Meter (UV and water spray). Representative results are summarized In Table 13. 

SODIUM, AZOTURE de (French) (26628-22-8) see sodium azide. SODIUM-2-BENZOTHIAZOLE-THIOATE (2492-26-4) C,HsNS2Na Combustible liquid (flash point >212°F/>100°C). Incompatible with strong oxidizers such as calcium hypochlorite strong bases, amines, amides, and inorganic hydroxides alcohols, aldehydes, mineral acids and acid fumes (releases heat). Concentrated aqueous solutions are corrosive. On small fires, use dry chemical powder (such as Purple-K-Powder), foam, water spray, or CO2 extinguishers.
