摘要： A novel process for the preparation of anthraquinoid intermediates and vat dyes by alkali fusion of suitable precursors in the presence of alcohol. The process comprises starting from benzanthrone, pyrazolanthrone or anthraquinone derivatives and carrying out the reaction in a machine with kneading action and in the presence of an alkali metal hydroxide and an aliphatic alcohol with a boiling point below 120 DEG C., at elevated temperature, to effect dimerization or cyclization, the weight ratio of alkali metal hydroxide to benzanthrone, pyrazolanthrone or anthraquinone derivative being

摘要： 286,602. I. G. Farbenindustrie Akt.- Ges. Dec. 14, 1925, [Convention date]. Divided on 262,819. Halogen- or methyl-dibenzanthrones are obtained by treating with alkaline condensing agents Bz1 : Bz1 -dibenzanthronyls containing halogen or methyl groups but not substituted in the 2- and 2 -positions. The reaction proceeds readily with alcoholic potash at temperatures slightly over 100‹ C. The products so obtained from halogen Bz1 : Bz1 -dibenzanthronyls differ in shade from those made by alkaline condensation of the appropriate halogen benzanthrones or halogen 2 : 2 -dibenzanthronyls and are also obtained in better yield. According to examples, (1) Bz2 : Bz2 -dimethyl - Bz1 : Bz1 - -dibenzanthronyl is heated with ethyl-alcoholic potash at 120-130‹ C. ; (2) 6 : 6 -dichlor-Bz1 : Bz1 -dibenzanthronyl is heated with caustic potash and aniline or ethyl alcohol; the product differs in dyeing proportions from that obtained from 6- chlorbenzanthrone bv the usual method. Bz2 : : Bz2 -Dimethyl-Bz1 Bz1 -dibenzanthronyl is obtained by treating with acid oxidizing agents the Bz2-methylbenzanthrone obtainable by condensing anthrone with alpha-methylacrolein. alpha-Methylacrolein is obtained by saponifying its dimethylacetal with dilute sulphuric acid. 6 : 6 -Dichlor-Bz1 : Bz1 -dibenzanthronyl is obtained by the oxidation of 6-chlorbenzanthrone.

摘要： 263,861. I. G. Farbenindustrie Akt.- Ges. Dec. 30, 1925, [Convention date]. Addition to 218,255. No Patent granted (Sealing fee not paid). Dibenzanthrone dyes. - Vat-dyestuffs are obtained by alkali-fusion of alkyl ethers of oxy- Bz1: Bz1 -dihenzanthronyls not substituted in the 2- or 2 -position; they are identical with those obtained according to the process of the parent Specification by alkali fusion of ethers of oxybenzanthrones. According to an example Bz2 : - Bz2 -dimethoxy-Fz1: Bz1 -dibenzanthronyl is fused with alcoholic potash. The Specification as open to inspection under Sect. 91 (8) (a) refers to the alkali fusion of ethers of oxydibenzanthronyls generally. This subject-matter does not appear in the Specification as accepted. Bz2: Bz2 -dimethoxy-Bz1 : Bz1 -dibenzanthronyl is obtained by heating Bz1-iodo-Bz2-methoxybenzanthrone with copper powder in an indifferent solvent. The Bz1-iodo-Bz2-methoxybenzanthrone may be obtained by nitrating Bz2- methoxybenzanthrone, reducing the nitro group to the amino group, diazotizing, and treating with potassium iodide.

摘要： A vat dye obtained by heating a condensation product, which itself has been prepared by heating 3,9-di-(1-anthraquinonylamino)-benz[d,e]anthrone in an aluminum chloride/picoline or aluminum chloride/quinoline melt in the presence of sulfuryl chloride or thionyl chloride, in a melt of an alkali metal hydroxide in an alcohol or glycol or aqueous glycol. The dye gives deep clear brown dyeings having good fastness characteristics.
