Specification
The chemical synonyms of 1-Ethylpiperidine (766-09-6) are 1-Ethvlpiperidine ; 1-Ethylpiperidene ; 1-Ethylpiperidin ; 1-Ethyl-piperidin ; Ethylpiperidylamnie ; Aethylpiperidin ; 1-Ethylpiperidine ; N-ethylpiperidine .It may cause toxic effects if inhaled or ingested/swallowed. Contact with substance may cause severe burns to skin and eyes. Fire will produce irritating, corrosive and/or toxic gases. Vapors may cause dizziness or suffocation. Runoff from fire control or dilution water may cause pollution.It may be ignited by heat, sparks or flames. Vapors may form explosive mixtures with air. Vapors may travel to source of ignition and flash back. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas. Vapor explosion hazard indoors, outdoors or in sewers. Runoff to sewer may create fire or explosion hazard. Containers may explode when heated. Many liquids are lighter than water.
