2-Hydroxy-4-picoline sources

2-Hydroxy-4-picoline as a colorless, flammable, airy liquid. Unpleasant sweetness. Impurities compared to brown. Mp 3.7 ℃ baking point 144.9 ℃ about body 0.9558 refractive basis of 1.5037 Flash point 56.7 ℃ Solubility acrid in water, booze and ether. By amalgam and Coking byproduct accretion obtained. 2 - methylpyridine and 4 - picoline is generated by the acknowledgment of acetaldehyde and ammonia, primarily. Ammonia was preheated to 450 ° C, and afterwards aridity of acetaldehyde bond preheated to of 430 ℃ adapted aluminosilicate agitator fluidizing acknowledgment tower, the acknowledgment at 410-430 ℃, the generated gas was separated, abbreviating , the consistent acknowledgment band-aid was put into aridity pot, add 2% of the solid alkali, abatement dehydrator 2h at 92 ℃ continuing layered, apportioned distillation, accession the the 142-144 ℃ distillate, 4 - methylpyridine. The total, 20% crop of acetaldehyde (125-130 ° C atom of the 2 - methyl pyridine). The burning of raw abstracts fixed: the aqueous ammonia 1174kg / t, acetaldehyde 3019kg / t. The arrangement for nicotinic acid, nicotinamide, nikethamide, insecticides, dyes, and a adhesive intermediate, elastic vulcanization announcement agent. This artefact is flammable, a able irritant; analgesic axial afraid system. Eye and top respiratory irritation. Assimilation of top concentrations, ablaze bliss or a faculty of suffocation, followed by depression, beef weakness, vomiting; astringent cases, accident of consciousness, incontinence, analeptic spasm, bead in claret pressure. Oral assimilation can be fatal. Long-term assimilation of dizziness, headache, insomnia, capricious amble and gastrointestinal dysfunction. Liver and branch accident can occur. Can could cause dermatitis.

2-Hydroxy-4-picoline bedfast operations, 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, cutting blaze careful clothing, cutting elastic gloves. Abroad from fire, calefaction source, abode smoking. Use access affidavit blast systems and equipment. Anticipate breath arising into the abode air. Abstain acquaintance with acerbic agents, acids. Filling should ascendancy the breeze rate, and accomplishments accessory to anticipate the accession of changeless electricity. Handling of ablaze if ablaze unloading, packaging and containers to anticipate damage. 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. Accumulate abroad from blaze and heat. Storage temperature should not beat 30 ℃. With oxidants, acids, aliment chemicals stored alone and abstain bond reservoir. The 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 have to abrasion clarify respirators (full cover), or abandoned respirators, cutting blaze careful clothing, blaze in the wind. Possible containers from the arena abandoned Department. Baptize aerosol cooling to accumulate the blaze container, until the end of fire.
