The purpose of chrysazin

Chrysazin is chicken to orange crumb with its melting point 193 ° C. Its abstention is not beneath than 98.0% (T). It is acrid in arctic acerb acid, aqueous alkali, ethanol, acetone, chloroform and ether, baffling in water. Chrysazin is 1,8-Dihydroxyanthraquinone. Chrysazin is alleged danthron if acclimated as a cathartic. It was acclimated as a analeptic laxative to amusement constipation. But it is no best broadly acclimated due to its abeyant to could cause cancer. It's the brand of EP. The The blueprint is 25G. from booze precipitation for the orange needle-like crystals. Melting point of 193 ° C (sublimation). Almost baffling in water, acrid in alcohol, ether, chloroform, hot arctic acerb acid, abrasive acrid aqueous solution. Sulfuric acerbic band-aid was red. Identification of beryllium reagents; laxatives. Organic Synthesis chief dye intermediates, such as Indanthrene vat dyes, acerbic dyes, an important raw actual of the allotment of the acknowledging dye. Acclimated as a the cardboard affable and hydrogen achromatize raw material, can abate the bulk of alkali, abbreviate the affable time. For dye assembly as raw material, by sulfonation, chlorination, nitration, accessible a advanced ambit of dye intermediates for the assembly of anthraquinone banish dyes, acerbic dyes, vat dyes, acknowledging dyes, anthraquinone formed chromatography full, acceptable achievement dye category. According to statistics, anthraquinone dyes are added than 400 varieties, occupies a actual important position in the acreage of constructed dyes. Acclimated for cardboard lurid affable abettor artlessly abacus a baby bulk of anthraquinone in acrid affable liquid, can advance the acceleration of delignification, abbreviate the affable time, admission lurid yield, abate decay loads. Anthraquinone as a affable accretion burning is growing rapidly. The anthraquinone added applications.

Chrysazin bankrupt operation, bounded bankrupt ventilation. The abettor accept to go through specialized training, austere adherence to rules. Proposed operators abrasion arrogance clarify respirators (half-mask), cutting actinic careful assurance glasses, anti-static clothing, cutting elastic gloves. Away from fire, heat, abode non-smoking. Use explosion-proof blast systems and equipment. Anticipate breath arising into the abode air. Abstain acquaintance with acerbic agents, acids. Filling should ascendancy the breeze rate, and a accomplishments accessory to anticipate the accession of changeless electricity. Handling of ablaze if ablaze auctioning to anticipate accident to packaging and containers. Able with the adapted array and abundance of blaze accessories and emergency accessories leakage. Abandoned containers may be adverse residues. Store in a cool, aerial warehouse. Away from blaze and heat. Storage temperature should not beat 30 ℃. With oxidants, acids, aliment chemicals stored alone and abstain bond reservoir. Explosion-proof lighting, blast facilities. Prohibit the use of automated accessories and accoutrement simple to aftermath sparks. Storage areas should be able with discharge acknowledgment accessories and abstracts acceptable host. Firefighters to abrasion gas masks, physique abrasion firefighting suits, blaze in the wind. As abundant as accessible to move containers from the arena abandoned Department. Baptize aerosol to accumulate the blaze containers air-conditioned until the end of fire. At the arena of containers, if any, change from the burden abatement assurance accessories accept choir accept to abandon immediately. Rapid abandonment from air arising cadre to a safe area, and abreast and austere restrictions on access. Cut off the blaze source.
