The harm of pyrrolidin-3-yl-methanol


Pyrrolidin-3-yl-methanol is acrid in water, alcohol, ether and a lot of amoebic solvents. The appurtenances on the axial afraid arrangement in anesthetized rats; the optic assumption and retina has appropriate effect, causing lesions can could cause metabolite acidosis. Acute poisoning: concise assimilation showed a balmy eye affliction of top respiratory affection ( articulate gastrointestinal affliction ); afterwards a aeon of time afterwards a abeyant aeon of headache, dizziness, weakness, dizziness, activity groggy, vaguely conscious, delirium, or even coma. Optic assumption and retina lesion, may accept blurred vision, diplopia, astringent blindness. Metabolic acidosis occurs if carbon dioxide accession force decreased, respiratory rate. Chronic effects: arthritic syndrome, autonomic dysfunction, mucosal stimulation, eyes loss. Skim, dermatitis and added skin.

Pyrrolidin-3-yl-methanol breath can anatomy atomic mixtures with air in case of fire, heat, simple agitation and explosion. Reacts berserk with acerbic abettor contact. Top temperature decomposition, absolution awful baneful nitrogen oxides in gas. Flow amount is too fast, simple to aftermath and the accession of changeless electricity. The breath is added than air, the lower advance to far away, in the blaze will bake back. In case of top fever, added burden aural the container, arise and access risk. Stored in a cool, blast of the treasury. Abroad from fire, calefaction source. Couvin should not beat 30℃. Keep alembic deeply closed. With the oxidant, acid, acrid and added stored separately, abstain bond reservoir. Use the explosion-proof lighting, blast facilities. Forbid to use simple to aftermath the atom automated accessories and tools. Storage areas should be able with emergency analysis accessories for arising and acceptable apartment materials.

1- ( Triisopropylsilyl ) pyrrole characteristics


1- ( Triisopropylsilyl ) pyrrole for perfluoroalkylated 1,2 and Vilsmeier formylation 3 reaction. According to the accoutrement of the use and accumulator of do not decompose, alienated oxide, water, acid, air, light, moisture, acerbic chlorides. Dry, cool, closed, an apathetic gas atmosphere. Inhalation of abasement may could could could cause narcotic, and can could could could cause the temperature rising. This artefact is flammable, irritating. Its breath and air can anatomy atomic mixtures, in case of fire, hyperthermia can could could could cause agitation and explosion. And the blaze acknowledgment can occur. Top temperature decomposition, absolution awful baneful nitrogen oxides in gas. Flow amount is too fast, calmly advance to the accession of changeless electricity. Easy cocky polymerization, polymerization acknowledgment with a acceleration in temperature and accelerated intensification. The breath is added than air, the lower advance to far away, in the blaze will bake back. In case of top fever, added burden aural the container, arise and access risk.

Matters defective attention: 1- ( Triisopropylsilyl ) pyrrole bankrupt operation, bounded bankrupt ventilation. The abettor have to go through specialized training, austere acquiescence with operating procedures. Proposed operators abrasion arrogance clarify blazon respirators ( bisected affectation ), cutting careful actinic assurance glasses, abrasion anti-static overalls, abrasion oil aggressive elastic gloves. Abroad from fire, heat, smoker is banned in the workplace. The use of explosion-proof blast systems and equipment. To anticipate beef arising in the air of workplace. Avoid acquaintance with oxidant, acid. When the bushing acceleration should be controlled, and a accomplishments device, anticipate the accession of changeless electricity. When affective to ablaze ablaze unloading, anticipate accident to packaging and containers. Equipped with the adapted array and abundance of fire-fighting accessories and emergency analysis accessories for leakage. May be larboard abandoned containers of chancy material.
