特徵

 

Chemical property  
It is volatile and extremely flammable, and the vapor and air form an explosive mixture, with an explosion limit of 1.3 ~ 8.4% (volume). It is easy to burn and explode in case of open fire and high heat. Contact with oxidant will cause strong reaction and even cause combustion. In the fire scene, heated containers are in danger of explosion. Its vapor is heavier than air, and can spread to a considerable distance at a lower place. It will catch fire and burn back when encountering a fire source. 

First aid measures 
Skin contact: take off contaminated clothes and wash skin thoroughly with soapy water and clear water.
Eye contact: lift the eyelids and rinse with flowing water or normal saline. See a doctor.
Inhalation: quickly leave the site to a place with fresh air. Keep the respiratory tract unobstructed. If breathing is difficult, give oxygen. If breathing stops, give artificial respiration immediately. See a doctor.
Ingestion: drink enough warm water to induce vomiting. See a doctor.

產品知識:

 

Cyclohexane is a cycloalkane with the molecular formula C6H12. Cyclohexane is non-polar. Cyclohexane is a colorless, flammable liquid with a distinctive detergent-like odor, reminiscent of cleaning products (in which it is sometimes used). Cyclohexane is mainly used for the industrial production of adipic acid and caprolactam, which are precursors to nylon.

Cyclohexyl (C6H11) is the alkyl substituent of cyclohexane and is abbreviated Cy.

On an industrial scale, cyclohexane is produced by hydrogenation of benzene in the presence of a Raney nickel catalyst. Producers of cyclohexane account for approximately 11.4% of global demand for benzene. The reaction is highly exothermic, with ΔH(500 K) = -216.37 kJ/mol). Dehydrogenation commenced noticeably above 300 °C, reflecting the favorable entropy for dehydrogenation.
