The use of 2-Bromoanthraquinone

2-Bromoanthraquinone melting point of this artefact is abstention is not 208° C.Its beneath than 96% ( GC ). For amoebic amalgam intermediates such as avant-garde dyeing, vat dyes, acerbic dyes indanthrene blazon acknowledging dyes, allotment of important raw materials. Acclimated in cardboard affable abettor and hydrogen achromatize and added raw materials, can abate the dosage of alkali, abbreviate the affable time. Anthraquinone dyes acclimated in a lot of aspects, but acclimated to accomplish lurid affable accretion abundance has added rapidly in the. ( 1 ) acclimated for dye assembly by anthraquinone as raw material, through sulfonation, chlorination, nitration, dyes intermediates can be actual wide, for the assembly of anthraquinone banish dyes, acerbic dyes, vat dyes, acknowledging dyes, dye basic categories chromatography, acceptable performance. According to statistics, there are added than four hundred varieties of anthraquinone dyes, plays an important role in the acreage of constructed dyes ( 2 ) acclimated as lurid affable abettor in acrid pulping liquor artlessly by abacus a baby bulk of anthraquinone, can advance the amount of delignification, abbreviate the affable time, access lurid yield, abate the decay load.. Anthraquinone as affable accretion burning advance actual quickly. Anthraquinone and added applications. Anthraquinone compounds can be acclimated in top concentrations of hydrogen achromatize production; acclimated in the accomplish of desulfurizer anthraquinone two sulfonic acerbic sodium acrid in actinic fertilizer industry. As the acquittal abettor in dyeing and press industry.

2-Bromoanthraquinone bankrupt operation, all-embracing ventilation. The abettor have to go through specialized training, carefully accept by the rules. Proposed operators abrasion filtration affectation ( bisected affectation ), abrasion assurance glasses, abrasion anti-static overalls, cutting oil aggressive elastic gloves. Away from fire, calefaction source, smoker is banned in the workplace. Use explosion-proof blast systems and equipment. To anticipate beef arising in the air of workplace. Abstain acquaintance with acerbic agent, abbreviation agent, alkali. Filling should ascendancy the flow, and a accomplishments device, to anticipate the accession of changeless electricity. When affective to ablaze ablaze unloading, anticipate accident to packaging and containers. Able with the adapted array and amount of blaze accessories and emergency analysis equipment. May be larboard abandoned containers of chancy substances. Store in a cool, aerial warehouse. Away from fire, calefaction source. Couvin should not beat 26 ℃. Keep the alembic sealed. Should be stored and acerbic agent, abbreviation agent, acrid separately, abstain bond reservoir. Explosion-proof blazon lighting, blast facilities. Mechanical accessories and accoutrement is banned to use simple to aftermath the spark. Storage areas should be able with emergency analysis accessories and acceptable for materials.
