    摘要: The present disclosure relates to a benzoyl substituted carbazole-dioxazine pigment and its preparation. The process involves benzoylation of 3-nitro-N-ethylcarbazole in monochlorobenzene using benzoylchloride and ferric chloride to yield 3-nitro-6-benzoyl-N-ethyl carbazole, which on catalytic hydrogenation and subsequent condensation with chloranil and cyclization yields benzoyl substituted carbazole-dioxazine pigment.

    摘要: A method is disclosed for producing cast iron or semi steel with reducing gas in a high pressure refractory lined shaft furnace using minimal or no coke Iron ore and slag are fed into the operative top zone of the shaft furnace while reducing gas which is generated in a refractory lined gasifier using preheated oxygen is fed through tuyere at the operative bottom and middle zones. The shaft furnace is operated at a high pressure to increase productivity and to facilitate use of the spent reducing gas downstream. Excess oxygen is fed into the shaft furnace to reduce the carbon content in the molten iron and generate semi steel. The size of the furnace is reduced The method is economical.

    摘要: The pigment is synthesized from 3-nitro-N-ethylcarbazole. The first step is nitration of 3-nitro-N-ethylcarbazole to form 3,6-dinitro-N-ethylcarbazole which is reduced to form 3-amino-6-nitro-N-ethylcarbazole. This amino compound is benzoylated to form 3-benzamido-6-nitro-N-ethylcarbazole which is then hydrogenated to form 6-amino-3-benzamido-N-ethylcarbazole. Condensation of 6-amino-3-benzamido-N-ethylcarbazole with chloranil provides an intermediate. Cyclization of the intermediate in the presence of a cyclization reagent provides the compound of Formula-I. The pigment has wavelength of maximum absorption (λmax) at 571 nm in dimethylformamide as a solvent.

    1 -C
    8 alkyl group, preferably R is an ethyl group, R
    1 is a chloro group, and R
    2 is a -NHC(=O)Ph group. The pigment is synthesized from 3-nitro-N-ethylcarbazole. The first step is nitration of 3-nitro-N-ethylcarbazole to form 3,6-dinitro-N-ethylcarbazole which is reduced to form 3-amino-6-nitro-N-ethylcarbazole. This amino compound is benzoylated to form 3-benzamido-6-nitro-N-ethylcarbazole which is then hydrogenated to form 6-amino-3-benzamido-N-ethylcarbazole. Condensation of 6-amino-3-benzamido-N-ethylcarbazole with chlroanil provides an intermediate. Cyclization of the intermediate in the presence of a cyclization reagent provides the compound of Formula-I. The pigment has wavelength of maximum absorption (λ
    max ) at 571nm in dimethylformamide as a solvent.
