Removal of refractory organics by aeration. IV. Solvent sublation of chlorinated organics and nitrophenols. Valsaraj, Kalliat T.; Wilson, David J. (Dep. Chem., Vanderbilt Univ., Nashville, TN 37235, USA). Colloids Surf., 8(2), 203-24 (English) 1983. CODEN: COSUD3. ISSN: 0166-6622. DOCUMENT TYPE: Journal CA Section: 60 (Waste Treatment and Disposal) Section cross-reference(s): 61 A math. model of mol. 88787-52-4 and 2610-16-4 are also in the experiment. adsorption at air-water interfaces in the removal of hydrophobic org. compds. from water or wastewater by solvent sublation (bubble transport into an overlying nonmiscible layer) is described. The model was tested on o- and p-dichlorobenzene and Aroclor 1254 (I) sublation into 2-octanol; on lindane, endrin, and I into mineral oil. Picric acid [88-89-1] and 2,4,dinitrophenol [51-28-5] were removed by complexing with hexadecyltrimethylammonium chloride [112-02-7]. Mass transfer rates were calcd. .

Microcrystallographic identification of 4-aminopyridine. Yalcindag, Orhan N. (Refik Saydam Cent. Inst. Hyg., Ankara, Turk.). J. Pharm. Belg., 38(6), 321-4 (French) 1983. 143-66-8 and 16941-12-1 which are cas registry numbers are also used here. CODEN: JPBEAJ. ISSN: 0047-2166. DOCUMENT TYPE: Journal CA Section: 64 (Pharmaceutical Analysis) Various reagents are described for the identification of 4-aminopyridine (I) [504-24-5] by microcryst. reactions. Picric [88-89-1], picrolonic [550-74-3], 5-nitrobarbituric acid [480-68-2], etc., were used as the reagents. The crystal forms of the ppts. obtained by the reactions were examd. microscopically. .
