    Abstract: PROBLEM TO BE SOLVED: To obtain an infrared-absorbing phthalocyanine, being the specific one, having extremely effective infrared-absorbing properties and useful as an infrared-absorbing agent for an infrared-absorbing ink, an printing ink, glasses, an agricultural sheet, a heat transfer printing, etc. SOLUTION: This infrared-absorbing phthalocyanine is the new one of formula I [A is a group of formula II (each of the rings B and C may be substituted by a 1-4C alkyl, a 1-4C alkoxy, nitro, hydroxysulfonyl, benzoyl or a benzene ring obtained by condensation cyclization at the ortho position; R is H or methyl), etc.; both Hs attaching to nitrogens may be replaced by copper, nickel, vanadyl, magnesium, AlCl, or zinc]. The infrared-absorbing phthalocyanine has an infrared absorption within a range of 720-1,100μm wavelength and is useful as an infrared-absorbing agent for an infrared absorbing ink, a printing ink, glasses, an agricultural sheet, a sheet-bonded plate glass, a heat transfer printing, etc. The compound is obtained by reacting compounds of formulas III and IV with a phthalocyanine substituted by a halogen.

    Abstract: Process for the preparation of 3-methylquinoline-8-carboxylic acid I and its derivatives by reacting o-toluidine II or its derivatives with methacrolein III in the presence of iodine or an iodine compound, in 70-90% by weight sulphuric acid, and oxidation of the resulting 3,8-dimethylquinoline IV or its derivatives with nitric acid in a solution of sulphuric acid in the presence of vanadium ions, characterised in that, in a first step, the by-products of the reaction are decomposed by oxidation in the reaction solution of 3,8-dimethylquinoline IV in sulphuric acid, the resulting 3,8-dimethylquinoline solution is concentrated by distillation, and subsequently the 3,8-dimethylquinoline is oxidised in situ with nitric acid to give 3-methylquinolinecarboxylic acid.

    Abstract: Prodn. comprises (a) treating a benzo isothiazole deriv. of formula (II) with a base; (b) reacting the resultant o-mercapto benzonitrile deriv. of formula (III) with a halomethyl cpd. of the formula Hal-CH2-R (IV); (c) treating the resultant 2'-cyanophenyl mercapto acetic acid deriv. of formula (V) with a base; (d) treating the resultant benzo(b)thiophene-2-carboxylic acid deriv. of formula (VI) with an acid; and (e) oxidising the resultant thio indoxyl deriv. of formula (VII) conventionally. New thioindigo cpds. are of formula (IA) and new o-mercapto benzonitrile derivs. (IIIA), 2'-cyanophenyl mercapto acetic acid derivs. (VA) and benzo(b)-thiophene-2-carboxylic acid derivs. (VIA) and thio indoxyl derivs. (VIIA) are of the given formulae with the same substits. as (IA): ring A has 0-4 substits. of 1-5C alkyl, alkoxy, alkylcarbonyl, alkoxy carboxyl, (di(1-5C))-alkylamino, phenyl, benzoyl, COOH, CN, NO2, NH2, OH and halogen and/or an condensed benzene ring, opt. substd. by 1-5C alkoxy, NO2, NH2 or OH; Hal = Cl, Br or I; R = COOH, a carboxylate anion, CN, 1-4C alkoxycarbonyl or aminocarbonyl. In (IA) and the other new cpds.: (a) R1 = Cl, R2 and R3 = H, Cl or Br and R2 not = H if R1 and R3 = Cl; or (b) R1 = CN, R2 = NH2 and R3 = H; or (c) R1 = H, R2 = NO2 and R3 = H, Cl or Br. USE/ADVANTAGE - (IA) are used for pigmenting lacquers, printing inks and plastics and for dyeing cellulosic textile material (claimed). The prepn. is esp. useful for producing (IA). It is economical, has a wide range of applications and forms (I) of high quality. It avoids difficulties in introducing specific substits. and environmental pollution in the prodn. of specific aniline derivs. normally used as starting material. (IA) are yellow, red, violet or brown pigments or vat dyestuffs with improved properties for application.
