1,8-Bis (hydroxymethyl) anthracene characteristics

1,8-Bis(hydroxymethyl)anthracene, C16H14O2, crystallized in the centrosymmetric amplitude accession P21 / n. The anthracene amount is about collapsed and shows acceptable acceding with the anthracene amount of anthracene-1 ,8-dicarboxylic acid. Anthracene-1, 8-dimethanol, C16H14O2, crystallized in the centrosymmetric amplitude accession P21 / n. The anthracene amount is about collapsed and shows acceptable acceding with the anthracene amount of anthracene-1 ,8-dicarboxylic acid. The melting point of this artefact is 217 ° C . Its abstention is not beneath than 98.0% (GC). It's the brand of EP.The blueprint is 1G. anthracene, absolute three ring polycyclic ambrosial hydrocarbons, atomic blueprint C14H10. It exists in atramentous tar. The three axial anthracene ring in a beeline line, is phenanthrene isomers. Anthracene as a achromatic cool crystals; has blue-violet fluorescence; melting point 216 ℃, baking point 340 ℃, the about body of 1.283 (25/4 ℃); simple sublimation; baffling in water, baffling in booze and ether, acrid in hot benzene . 9,10 anthracene bit college actinic activity, with nitric acerbic blaze to aftermath 9,10 - anthraquinone (see anthraquinone structure), is an important constructed intermediates anthraquinone dyes; abridgement with sodium and booze to aftermath 9, 10 - dihydro-anthracene; chlorination accomplish 9,10 - anthracene dichloride, the closing allotment of the heating accident of hydrogen into 9 - chloroanthracene; anthracene can be acclimated as a conjugated diene, with maleic anhydride and the like in 9,10 occurred at a Diels - Alder reaction. Acclimated as a bright actual (such as a blaze counter), in accurate for blanket (such as for UV absorption). For the accomplish of anthraquinone dyes. Also acclimated as pesticides, fungicides, like gasoline retarder.

1,8-Bis(hydroxymethyl)anthracene authentic non-toxic. Industrial articles absolute phenanthrene, carbazole and added impurities, toxicity was decidedly increased. Since the breath burden is actual low, so the contagion by assimilation is unlikely. On the derma and close film irritant; calmly could cause photosensitive dermatitis. Migration in the ambiance several abstracts prove that polycyclic ambrosial hydrocarbons (PAHs) can be biodegradable. Low atomic weight polycyclic ambrosial hydrocarbons (PAHs) such as naphthalene, acenaphthene, acenaphthylene in beginning studies can be rapidly degradable. Initial absorption of 5 ~ 10mg / L of liquid, aural 7 canicule of added than 90% of polycyclic ambrosial (PAHs) are biodegradable. High atomic weight polycyclic ambrosial hydrocarbons (PAHs) such as fluoranthene, benzo (a) anthracene, flexion, benzo (a) anthracene and pyrene and added hard-biodegradable. Isolation arising attenuated area, amid about the admonishing signs, the proposed emergency cadre cutting masks, abrasion adapted dress. Do not absolute acquaintance with leakage, to abstain dust, anxiously scan, bag placed alteration to a safe place. If ample spills, recycling or accumulating of complete decay treatment. Closed operation, bounded bankrupt ventilation. The abettor have to go through specialized training, austere adherence to rules. Proposed operators abrasion arrogance clarify respirators (half-mask), cutting actinic careful assurance glasses, abrasion anti-static overalls, cutting elastic gloves. Keep abroad from fire, heat, abode 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 unloading, packaging and containers to anticipate damage. Equipped with the adapted array and abundance of blaze accessories and emergency accessories leakage. Empty containers may be adverse residues.
