The 1,8-Dichloroanthraquinone nature

The 1,8-Dichloroanthraquinone melting point is 202 ° C. Irritation. Its abstention not beneath than 95.0% (GC), and the blueprint for 25G or 250G. This artefact is ablaze chicken aggravate crystal, acrid of nitrobenzene and hot toluene, hardly acrid in ethanol. Chicken in concentrated sulfuric acid. Acclimated in the accomplish of vat dyes, banish dyes, amoebic pigments and pharmaceutical. The all-inclusive majority of anthraquinone for dye aspects, but are acclimated in accomplishment lurid digester abetting dosage has been accretion rapidly. (1) anthraquinone as raw actual for the assembly of dyes, sulfonation, chlorination, nitration, etc., accessible to a advanced ambit of dye intermediates for the assembly of anthraquinone banish dyes, acerbic dyes, vat dyes, acknowledging dye to anatomy chromatographic full, acceptable achievement dye classes. According to statistics, added than 400 varieties of anthraquinone dye, occupies a actual important position in the acreage of constructed dyes. (2) as the abettor of cardboard lurid affable artlessly abacus a baby bulk of anthraquinone in acrid affable liquid, can advance the delignification rate, abbreviate the affable time, admission lurid yield, abate decay loads. . Anthraquinone as a affable accretion burning is growing fast. Anthraquinone, there are added fields of application. Anthraquinone compounds can be acclimated in top concentrations of hydrogen achromatize production; in the fertilizer industry for the accomplish of desulfurizing abettor anthraquinone disulfonate. Dyeing industry as acquittal aids. As dye average PULP and hydrogen achromatize raw materials. Affable accretion acclimated as lurid and paper, you can abate the acrid charge, abbreviate the affable time.

1,8-Dichloroanthraquinone bound aperture attenuated areas abandoned cadre to a safe area, and isolation, austere restrictions on access. Cut off the blaze source. Recommended emergency cadre abrasion cocky absolute burden respirator, cutting careful clothing. As far as accessible to cut off the antecedent of leakage. To anticipate the breeze of sewers, flood acquittal arroyo bound space. A baby leak: sand, dry adhesive or soda ash mixture. Also can bathe with affluence of water, ablution baptize adulterated into the wastewater system. Large spills: amalgam barricade or dig a hole. Pump is transferred to the catchbasin or absolute collector, a abode to accord with recycled or transported to the decay disposal. Blaze cadre have to abrasion a respirator ( abounding cover) or abreast respirator, abrasion full-body blaze careful clothing, blaze in the wind. As far as accessible the argosy to an accessible area. Keep the blaze cooling baptize container, until the end of the fire. In the barge in blaze arena if birthmark or from complete burden abatement device, have to abandon immediately. Abolition media: baptize spray, foam, dry powder, carbon dioxide, sand. Prohibit the use of acid-base blaze abolition agent. : stored in a cool, aerial warehouse. Away from fire, calefaction source. Couvin should not beat 30 ℃. Should be kept abstracted from the acerbic agents, acids, comestible chemicals, abstain bond reservoir. Explosion-proof blazon lighting, blast facilities.
