Monoazo disperse dyes for synthetic fibers. (Mitsui Toatsu Chemicals, Inc., Japan). Jpn. Kokai Tokkyo Koho JP 60086167 A2 15 May 1985 Showa, 5 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: ICM: C09B029-033. APPLICATION: JP 83-194349 19 Oct 1983. DOCUMENT TYPE: Patent CA Section: 41 (Dyes, Organic Pigments, Fluorescent Brighteners, and Photographic Sensitizers) Title dyes I (R = H, Me, Cl, NHAc, NHCOEt; R1 = Me, Et; R2 = H, Me) were prepd. and used for dyeing polyester fibers in red to purple shades with excellent fastness and alkali dischargeability. Thus, tetrahydrofurfuryl alc.In this experiment, several chemicals are used like 97-99-4 [97-99-4] was treated with chloroacetyl chloride [79-04-9] at 80° for 2 h to give tetrahydrofurfuryl chloroacetate [702-26-1] which was treated with m-aminoacetanilide [102-28-3] in the presence of soda ash and KI to obtain a coupler which was then coupled with diazotized 2-amino-3-cyano-4-methyl-5-carbethoxythiophene [23903-46-0] to give I (R = AcNH; R1 = Et; R2 = Me) [98257-23-9], reddish purple on polyester fibers, with better fastness to light, sublimation, and water than II (R = R2 = Me; R1 = Et). .

Sulfonamide nonaqueous injections. Goellner, Bruno; Heitmann, Hans Henrik (Chassot und Cie A.-G., Switz.). Patentschrift (Switz.) CH 641348 A 29 Feb 1984, 2 pp. (German). (Switzerland). CODEN: SWXXAS. CLASS: IC: A61K031-18; A61K031-635; A61K031-505; A61K009-08. APPLICATION: CH 78-12432 6 Dec 1978. DOCUMENT TYPE: Patent CA Section: 63 (Pharmaceuticals) Stable injections of sulfonamides and sulfonamide potentiators contain water-miscible org. solvents and no water. A soln. of 200 mg sulfadimidine (I) [57-68-1] in DMF [68-12-2] 160, EtOH [64-17-5] 55, and polyethylene glycol 400 [25322-68-3] 217 g was mixed with a soln. of 40 g trimethoprim (II) [738-70-5] in 160 g dimethylacetamide [127-19-5] and 220 g tetrahydrofurfuryl alc. [97-99-4]. The mixt. was adjusted to pH 10 with diethanolamine.
