페인트 드럼 또는 유조선 포장으로 밀봉. 스토리지 건조 하 고 차가운 장소에 배치 되어야 합니다, 그리고 창 고 가수분해를 방지 하기 위해 물과의 접촉을 피하기 위해 환기 시설이 있어야 합니다.화학적 성질
n-Heptane is a flammable liquid, present in crude oil and widely used in the auto- mobile industry. For example, as a solvent, as a gasoline knock testing standard, as automotive starter fl uid, and paraffi nic naphtha. n-Heptane causes adverse health effects in occupational workers, such as CNS depression, skin irritation, and pain. Other compounds such as n-octane (CH 3 (CH 2 ) 6 CH 3 ), n-nonane (CH 3 (CH 2 ) 7 CH 3 ), and n-decane (CH 3 (CH 2 ) 8 CH 3 ) have different industrial applications. Occupational workers exposed to these compounds also show adverse health effects. In principle, manage- ment of these aliphatic compounds requires proper handling and disposal to avoid health problems and to maintain chemical safety standards for safety to workers and the living environment.물리적 성질
Clear, colorless, very flammable liquid with a faint, pleasant odor resembling hexane or octane. Based on a triangle bag odor method, an odor threshold concentration of 670 ppbv was reported by Nagata and Takeuchi (1990).용도
heptane is a solvent and viscosity-decreasing agent.정의
heptane: A liquid straight-chainalkane obtained from petroleum,C7H16; r.d. 0.684; m.p. -90.6°C; b.p.98.4°C. In standardizing octanenumbers, heptane is given a valuezero.생산 방법
Heptane is produced in refining processes. Highly purified heptane is produced by adsorption of commercial heptane on molecular sieves.일반 설명
