Modification of the surface of porous polymer sorbents in a glow discharge plasma: Gil'man, A. B.; Zakharova, T. K.; Volkov, S. A.; Kolotyrkin, V. M.; Grigor'eva, G. A.; Sakodynskii, K. I.; Tunitskii, N. N. (Nauchno-Issled. Fiz.-Khim. Inst. im. Karpova, Moscow, USSR). Zh. Fiz. Khim., 53(10), 2621-4 (Russian) 1979. CODEN: ZFKHA9. ISSN: 0044-4537. DOCUMENT TYPE: Journal CA Section: 36 (Plastics Manufacture and Processing) By glow discharge treatment of Polysorb 1 [9003-70-7] sorbent in the presence of vapors of N-contg. org. compds. led to modification of its porous surface due as the result of formation of new functional groups on the sorbent surface. Such modification led to an increase in the retention time of polar substances. The sp. surface of the sorbent decreased from 224 to 147 m2/g on treatment in the presence of a-vinylpyridine (I) [100-69-6] and 2-(1,2-difluoro-2-chlorovinylpyridine) [395-02-8] and to 145 and 154 m2/g in the presence of N-methylpyrrolidone (II) [872-50-4] and m-fluorobenzoylamine [100-82-3], resp. The pore size of the sorbent increased from 20 to 75 ? in the presence of I. The highest retention time for acetonitrile, Me2CO and Et2O was obsd. for the sorbent treated with II.

Development of absorption refrigeration units for cold storage of agricultural products: Development of absorption refrigeration units for cold storage of agricultural products. Borde, I.; Jelinek, M. (Inst. Appl. Res., Ben-Gurion Univ. Negev, Beer-Sheva, Israel). Int. J. Refrig., 10(1), 53-6 (English) 1987. CODEN: IJRFDI.Several substances with their cas registry numbers 143-24-8 and 75-45-6 may be metioned in this study. ISSN: 0140-7007. DOCUMENT TYPE: Journal CA Section: 52 (Electrochemical, Radiational, and Thermal Energy Technology) Section cross-reference(s): 48, 69 The best refrigeration performance characteristics in terms of coeff. of performance, circulation ratio, and sp. heat loads were shown by the combinations R 22 [75-45-6]-DMF [68-12-2], followed by R 22-N-methyl-2-pyrrolidone [872-50-4], R 22-di-Me methylphosphonate [756-79-6], R 22-tetraethylene glycol di-Me ether [143-24-8], and finally by R 22-methyl-e-caprolactam [1985-48-4]. On the basis of the research performed, a 15-ton refrigeration prototype unit for the storage of agricultural products was constructed. It operates at a coil temp. of -3° and maintains the storage chamber at 5°. Hot water is supplied at 95-98°, and cooling water is provided at 26°. .
