Evaluation of some insect repellent formulations. Part-I. Water soluble ointment bases. Sharma, Rakesh Kumar; Jain, Surindra K.; Kumar, Santosh; Rao, K. M. (Def. Res. Dev. Establ., Gwalior 474902, India). Indian J. Hosp. Pharm., 21(1), 26-9 (English) 1984. CODEN: IJHPBU. ISSN: 0019-526X. DOCUMENT TYPE: Journal CA Section: 5 (Agrochemical Bioregulators) N,N'-Diethylphenylacetamide (I) [2431-96-1], prepd. by treating 1 mol phenylacetyl chloride [103-80-0] with 2 mol Et2NH [109-89-7], was incorporated at various concns. (3-20%) as an insect repellent in water-sol. ointment bases. A vanishing cream contg. 20% I had a protection time of 6 h against Aedes aegypti, as compared to 1 h when using 3% I. I formulations contg. some essential oils had a prolonged protection time.

Desulfurization of gases with an amine-containing wash solution

Desulfurization of gases with an amine-containing wash solution. Doerges, Alexander; Schlauer, Johann; Kriebel, Manfred; Hude, Anton (Metallgesellschaft A.-G. , Fed. Rep. Ger.). Ger. Offen. DE 3242277 A1 17 May 1984, 10 pp. (German). (Germany). CODEN: GWXXBX. CLASS: IC: B01D053-14; C10K001-08. APPLICATION: DE 82-3242277 16 Nov 1982. DOCUMENT TYPE: Patent CA Section: 51 (Fossil Fuels, Derivatives, and Related Products) Predesulfurized gases are subjected to fine desulfurization in an app. that contains a cooling-condensation zone above a wash zone. Thus, a gas contg. <5 mg H2S and COS/m3 is mixed with a C1-3 alc. and a secondary amine (e.g., Et2NH [109-89-7], at > (molar) amine-(H2S + COS)) and washed. Above the wash zone, a cooling zone condenses alc. and amine, which fall into the wash zone for better washing.
