Description
Technical field
The present invention relates to Vat Olive R technical field, specially a kind of Vat Olive R production technology.
Background technology
Nineteen ninety builds up 50 tons of Vat Olive Rs of annual output(Vat Olive R is " Vat Black 27 100 ")Workshop, then formally
Go into operation, waken up with 1- amino anthracenes by the production technology of FIATBB and 1-chloroanthraquinone is contracted as primary raw material in nitro benzene solvent
Close, then Jing is nitrified, reduced, o-dichlorohenzene makees the Benzenecarbonyl chloride. acylation of solvent and closed loop is aoxidized, in order to get rid of poisonous Nitrobenzol
Solvent replaced liquid phase condensations in 1993 using solid phase condensation, but the shortcoming of this process route is that operation is long, is related to primary product
Plant many.
After 1997, it is referred from written by Japanese thin Tian Feng《Dyestuff chemistry manufacture is theoretical》Data, with Isosorbide-5-Nitrae diaminoanthraquinone-
Wake up and 1- amino anthraquinones are primary raw material, and with manganese dioxide make oxidant respectively, sodium hydrosulfite is compiled for the glue oxygen of reducing agent and closes work
Skill, and make enemy's agent for Benzenecarbonyl chloride. with benzoic acid in oleum medium with reference to United States Patent (USP), thus make enemyization and close
Ring is incorporated in one procedure and carries out.
After 2009, through technological innovation, and manganese dioxide and sodium hydrosulfite is replaced to define current existing using sodium chlorate
The easy production process route of comparison employed in production.
