Dimethylterephthalate production from polyester wastes: Dimethylterephthalate production from polyester wastes. Delattre, Jacques; Raynaud, Roland; Thomas, Claude (Rhone-Poulenc-Textile, Fr.). Ger. Offen. DE 2657044 23 Jun 1977, 16 pp. (German). (Germany). CODEN: GWXXBX. CLASS: IC: C07C069-82. PRIORITY: FR 75-38775 16 Dec 1975. DOCUMENT TYPE: Patent CA Section: 35 (Synthetic High Polymers) Section cross-reference(s): 25 Dimethyl terephthalate (I) [120-61-6] is prepd. from bis(hydroxyethyl) terephthalates, obtained by glycolysis of waste polyester fiber or film, followed by methanolysis with Mg(OMe)2 [109-88-6] catalyst under essentially anhydrous conditions. Thus, refluxing 1 part 97% poly(ethylene terephthalate) [25038-59-9] waste, 1 part HOCH2CH2OH, and 100 ppm Mg(OAc)2.4H2O gives a soln. of bis(2-hydroxyethyl) terephthalate [959-26-2] which is concd. to 70%. Heating this soln. with 4.035 parts MeOH and 0.0048 parts Mg(OMe)2 2 h at 70.degree. and 4 h at 25.degree. gives 0.940 part colorless I, m. 140.7.degree., acidity 0.003% (as HOAc).Except for chemicals metioned above, 41138-37-8 is also used. .

CLASS: IC: C08F010-00; C08F004-02; C08F004-64. APPLICATION: JP 82-42984 19 Mar 1982. DOCUMENT TYPE: Patent CA Section: 35 (Chemistry of Synthetic High Polymers) a-Olefins were polymd. using catalysts contg. alkyl- or arylmagnesium oxides deposited on oxides of Group II-IV metals in org. solvents, electron donors, and tetravalent Ti halides; org. Al compds.; and org. acid esters. Thus, 10 g SiO2 was kept for 2 days at room temp. in 80 mL MeOH soln. (7.6 mg/mL) of Mg(OMe)2 [109-88-6]. The white solid (5 g) obtained, 0.5 mL Et benzoate [93-89-0], and 50 mL n-heptane were refluxed 2 h, decanted, and kept 2 h at 80° with TiCl4 to give a solid catalyst component (A, 3.9 wt.% Ti and 4.2 wt.% Mg). 93-89-0 and 99-75-2 which are cas registry numbers of chemicals are mentioned. Propylene was polymd. for 2 h at 70°, 0.7 kg/cm2 H partial pressure, and 2 kg/cm2 total pressure in an autoclave contg. 1 L n-heptane, 0.3 g A, 2 mL iso-Bu3Al [100-99-2], and 0.2 mL Me p-toluate [99-75-2] to give isotactic polypropylene [25085-53-4] (97.2 wt.% boiling n-heptane extn. residue). .
