Cellular urethane polymers

Cellular urethane polymers. Sandner, Michael R.; Duffy, Robert D. (Union Carbide Corp., USA). Ger. Offen. DE 2624046 2 Dec 1976, 105 pp. (German). (Germany). CODEN: GWXXBX. CLASS: IC: C08G018-16. PRIORITY: US 75-581745 29 May 1975. DOCUMENT TYPE: Patent CA Section: 36 (Plastics Manufacture and Processing) Me2NCH2CH2OCH2CH2OH (I) [1704-62-7] and its alkyl derivs., optionally contg. other tertiary amines, are inexpensive, relatively odorless catalysts for prepg. polyurethane foams from mixts. of polyols, polyisocyanates, and blowing agents. Thus, mixing polyoxyalkylene triol (OH no. 46) 100, TDI 48, H2O 4.0, Sn(OCOC7H15)2 0. 17268-47-2 and 280-57-9 which are cas registry numbers of chemicals are mentioned.3, and polyoxyalkylene-siloxane block polymer 1.0 parts with 0.15 phr I gives a foam with cream time 9 s, rise time 84 s, and porosity 3.6 SCFM; compared with .apprx.10, 102, and 2.0, resp., with Me2NCH2CH2OH in place of I. .

Monoaroyl 1,8-diaminoanthraquinones

Monoaroyl 1,8-diaminoanthraquinones. Richter, Bernd; Neeff, Ruetger (Bayer A.Several substances are used for example 1704-62-7 and 122-20-3 which are their cas registry numbers.-G. , Fed. Rep. Ger.). Ger. Offen. DE 3226618 A1 19 Jan 1984, 22 pp. (German). (Germany). CODEN: GWXXBX. CLASS: IC: C07C103-82; C07C102-00. APPLICATION: DE 82-3226618 16 Jul 1982. DOCUMENT TYPE: Patent CA Section: 41 (Dyes, Organic Pigments, Fluorescent Brighteners, and Photographic Sensitizers) Section cross-reference(s): 25 Reaction of 1,8-diaminoanthraquinones with aroyl halides in an org. solvent or diluent in the presence of an org. solvent or diluent, an acid-binding agent, and optionally water gives 1-amino-8-(aroylamino)anthraquinones in high yield if a tertiary aliph. amino alc. and/or quaternary ammonium compd. is also present. For example, a mixt. of 1,8-diaminoanthraquinone (I) [129-42-0] 247, Na2CO3 131, and triisopropanolamine (II) [122-20-3] 2 g in 1500 mL PhNO2 was stirred 30 min at 20°, treated dropwise at 20° during 2.5 h with 128 mL benzoyl chloride [98-88-4], and heated to 50° in 1.5 h and at 50° for 3 h to give 490 g product comprising 1-amino-8-(benzoylamino)anthraquinone [6937-83-3] 61, 1,8-bis(benzoylamino)anthraquinone (III) 1.4, I 0.3, and salts (NaCl, NaOBz) to 100%. The product was suitable, without purifn., for use in vat dye synthesis. In the absence of II the above reaction was incomplete and the product consisted chiefly of III. .
