Thermodynamics of reactions of 1,4-butanediol with terephthalic acid and its derivatives: Thermodynamics of reactions of 1,4-butanediol with terephthalic acid and its derivatives. Karyakin, N. V.; Shvetsova, K. G. (Gor'k. Gos. Univ., Gorkiy, USSR). Deposited Doc., SPSTL 861 Khp-D82, 14 pp. Avail. SPSTL (Russian) 1982. DOCUMENT TYPE: Report CA Section: 35 (Chemistry of Synthetic High Polymers) The enthalpy, entropy, and free energy are detd. for the polycondensation of 1,4-butanediol (I) [110-63-4] with terephthalic acid [100-21-0], terephthaloyl chloride [100-20-9], and di-Me terephthalate (II) [120-61-6] as well as for the polymn. of II with adipic acid [124-04-9]. Thermodn.In this experiment, several chemicals are used like 59822-52-5 and 24968-12-5 functions are also given for the monomers and poly(butylene terephthalate) [24968-12-5] and for the dehydration of I to THF [109-99-9]. .

Microcapsule walls obtained by crosslinking of milk proteins: Microcapsule walls obtained by crosslinking of milk proteins. Levy, Marie Christine; Guerin, Daniele (Centre National de la Recherche Scientifique, Fr.). Eur. Pat. Appl. EP 93668 A1 9 Nov 1983, 20 pp. DESIGNATED STATES: R: AT, BE, CH, DE, GB, IT, LI, LU, NL, SE. (French). (European Patent Organization). CODEN: EPXXDW. CLASS: IC: B01J013-02; A61K009-50. APPLICATION: EP 83-400862 29 Apr 1983. PRIORITY: FR 82-7735 4 May 1982. DOCUMENT TYPE: Patent CA Section: 63 (Pharmaceuticals) External walls of microcapsules are obtained by the interfacial crosslinking of milk proteins using reactive bifunctional acylating agents or dialdehydes such as glutaraldehyde [111-30-8]. The resulting microcapsules are spherical with a diam. 25-300 m. Thus, 3 mL milk is added to a mixt. of CHCl3-cyclohexane (1:4) and Span 85 and the mixt. homogenized, and stirred and treated with a satd. soln. of terephthaloyl chloride [100-20-9]. The mixt. 26471-62-5 and 111-30-8 are also in the experiment. is stirred, mixed with 30 mL of the above solvent mixt., and the resulting microcapsules are dispersed and centrifuged. The microcapsules are then washed with alc. and later suspended in distd. water. The microcapsules obtained are yellow, have a diam. 25-300 m, contain milk lipids in fine globular form of 1-2 m diam. The above suspension was lyophilized to yield a powder. The gastroresistance of the powder and its enteric soly. were demonstrated. .
