Opium. An extract of opium, containing a mixture of the total alkaloids of opium, is available as an alcoholic aqueous solution. It is available us Deudorixed Opium Tincture (IS mg/mL of morphine base) and Paregoric (2 mg/mL of morphine base). These are used primarily for the treatment of diarrhea. 

Properties Transparent, odorless crystals efflorescing on exposure to air or white powder sweetish metallic taste. D 2.6, at 100C loses all its water. Soluble in water, glycerol insoluble in alcohol. Aqueous solution is slightly acid. 

Properties White powder. Mw 81.97, mp 1650C. Soluble in water insoluble in alcohol aqueous solution strongly alkaline. 

Typical organic solvents for diffusion adhesives are methylene chloride (for PC, ABS, PMMA), xylene, cyclohexanone (ABS), tetrahydrofurane (THF adhesive for PVC-U, ABS, SAN, SB), ethyl and butyl acetate (ABS), alcoholic-aqueous solution of resorcin and phenol (for PA 6, PA 6.6 and PA 12), DMF, higher primary alcohols, A-methyl-pyrrolidone (for PA 11), methylethyl ketone (for CA, CAB, CP, CN, ABS, SAN, SB, PMMA), xylene, toluene for PS. It is remarkable that so much of these solvents is used despite the known high hazard potential. 

CAA (372-09-8) Combustible solid (flash point 226°F/107°C). Dust or powder may form explosive mixture with air. Reacts with water, forming a medium-strong acid solution. Incompatible with oxidizers, strong acids, alkalis, reducing agents, furfuryl alcohol. Aqueous solution is incompatible with sulfuric acid, alkalis, ammonia, aliphatic amines, alkanolamines, alkylene oxides, amides, epichlorohydrin, organic anhydrides, isocyanates, vinyl acetate. Attacks metals in the presence of moisture. 

Saccharose crystallizes in small, white, monoclinic prisms or, ns sugar-candy, in large, yellowish, transparent crystals sp. gr. l.COO. It is very soluble in water, dissolving in about one-third its weight of cold water, and more abundantly in hot water. It is insoluble in absolute alcohol or ether, and its solubility in water is progressively diminished by the addition of alcohol. Aqueous solutions of cane-sugar are dextrogyrous, [a]o=- -73 .8. 

Concentration of polyvinyl alcohol aqueous solutions to give satisfactory core washes with adequate viscosity depends on molecular weight of the polymer. Polyvinyl alcohol solutions can also be used as a mixture with zircon or graphite core wash. 

Still another method is to allow the aldehydes, which are contained in the crude 2,6-NDA, to react with a sulfite to give aldehyde adducts, and then dissolving the aldehyde adducts in the alcohol aqueous solution. ... 

Acetyl Water, alcohols, aqueous solution of Water above 24°C (36)... 

Those reactions only happen in the alcohol aqueous solution of monohydric alcohol nitrates. It should be noted that methyl nitrate cannot be reacted in the first path, while tert-butyl nitrate cannot be hydrolyzed in the third path. The product amount of methyl nitrate hydrolysis through the third path is very small. Only 4 % ethyl nitrate is hydrolyzed in the first and second paths. The other nitrate esters would be completely hydrolyzed in the first path. The ratio of the reaction velocity for three reaction paths is 70 7 1. 

Superiority of PI membranes subjected to PV over other polymeric membranes has been highlighted by Jiang et al. (2009). Membranes prepared from soluble Pis derived from 4,4 -diamino-3,3 -dimethyldiphenylmethane was used as a PV membrane for EtOH-water mixture (Wang et al.2006). The average value of the separation factor and total permeation flux were 46-108 and 660-1380 g/m h, respectively. Yanagishita et al. (1995) used asymmetric PI (aromatic) membranes (flat sheet) prepared by a phase inversion process, for the separation of alcohol solution by PV. The membrane exhibited separation factors of afHjO/EtOH) = 900 and a(H20/2-Pr0H) = 11,000 with a flux of 0.45 kg/m h for 95 vol% alcohol aqueous solution at 60°C. The membrane showed stable performance for 3 months.
