This makes it very suitable for exterior storage even in cold weather. Isobutane is particularly valuable in a refinery as a feedstock to the alkyaltion unit, where it is combined with either propylene or butylene to make alkylate (a high-quality gasoline blend stock ). The chemical formula of r-600a refrigerant is similar to butane, natural gas. Material Name: ISOBUTANE SDS ID: MAT11600 _____ Page 1 of 8 Issue date: 2022-01-04 Revision 7. It can asphyxiate by the displacement of air. When a natural-gas leak is detected and shut off in a room, the gas can be removed by opening an upper window. Average mass 58. for this species. The carbon atom coupled to hydrogen and two -CH 3 groups is the structural unit of the 'iso' group. Concn of the cmpd in lung tissue were max within 1 hr of death & decreased thereafter depending on the degree of putrefaction. Isobutane adalah gas transparan yang tidak berwarna, tidak berbau. Tidak seperti n-butana, itu adalah gas yang tidak berbau. 주로 에어로졸 스프레이, 냉장고의 냉각제 (또는 냉매)등으로 사용된다. Este artigo sobre Química é um esboço.
