    摘要: PROBLEM TO BE SOLVED: To obtain a disperse dye which effects a satisfactory dying even under a severe condition at a high temperature by employing a crystalline monoazo disperse dye in which a certain peak appears in an X-ray diffraction analysis with Cu-Kα ray. SOLUTION: This is a crystalline monoazo disperse dye in which a strong peak appears at a 2θ of 5.3-in the diffraction angle 2 θ range of 5 deg.-30 deg.. In this dye, weak peaks also appear at 9.2-,12.9-, 16.0-, 16.3-, 17.6-, 18.8- and 21.1-. A monoazo disperse dye having such a crystalline form is obtained by, directly or after a neutralization at pH 6-7, agitating a reaction mass for a typical monoazo dye at a temp. of 50-130 deg.C for 0.5-30 hr. Alternatively, the monoazo disperse dye is obtained by dispersing a cake which is a filtered solid compound separated from a reaction mass into an aqueous medium of pH 7.5-12.0 and agitating it at a temp. of 60-130 deg.C for 0.5-30 hr.

    摘要: PURPOSE:To provide the novel compound having an action to more specifically relax bronchial smooth muscles than vascular smooth muscles, and useful as an antiasthmatic medicine capable of dilating bronchial tubes without being accompanied by the lowering in blood pressure. CONSTITUTION:This compound is N-Cyano-N'-(2-nitroethyl)-2-(5-nitrothiophene) carboximidamide of formula I. The compound is obtained by treating 2-cyano-5- nitrothiophene of formula II with hydrogen chloride gas in a propanol solution, reacting the obtained propyl=2-(5-nitrothiophene)carboximidate with cyanamide in a buffer solution preferably comprising a phosphoric acid solution, and subsequently reacting the obtained propyl=N-cyano-2-(5-nitrothiophene)carboximidate of formula III with 2-nitroxyethylamine.

    摘要: NEW MATERIAL:A compound of formula I [X1 and X2 are each H, halogen, formyl, NO2, CN, alkoxy, alkylthio, (substituted)alkyl, etc.; X3 and X4 are each H, halogen or (substituted)alkyl; R is H, (substituted)alkyl or (substituted)phenyl; Y is NR R (R and R are each H, alkyl, alkenyl, etc.) or OR (R is H or alkyl)]. EXAMPLE:2-[p-(2-Nitro-3-thienyloxy)phenoxy]ethyl butyrate. USE:A bactericide/fungicide. PREPARATION:For example, the objective compound of the formula I can be obtained by a reaction, in the presence or absence of a solvent (e.g. benzene, toluene, xylene), between (A) a halogenothiophene compound of formula II (X5 is halogen) and (B) a phenol derivative of formula III (M is H or alkali metal).
