Heptana(CAS#142-82-5)

kounga
Te wai kore tae. Kare e rewa ki te wai, ka whakarewahia ki te waipiro, ka uru ki te etera, te chloroform. Ko tana kohu he ranunga pahū me te hau, ka puta te ngingiha me te pahūtanga mena ka tuwhera te mura me te wera nui. Ka kaha te tauhohenga ki nga waiora.

Tikanga
Ka taea te purea te n-heptane-ahumahi ma te horoi i te waikawa sulfuric concentrated, methanol azeotropic distillation me etahi atu tikanga.

whakamahi
Ka whakamahia hei reagent tātari, he paerewa whakamatautau patoto miihini penehīni, he matū tohutoro mo te tātari chromatographic, me te whakarewa. Ka whakamahia hei paerewa mo te whakatau i te tau octane, ka taea hoki te whakamahi hei waipiro, te whakarewa me te rauemi mata mo te whakahiato waro.

haumarutanga
kiore werohia LD50: 222mg/kg; kiore i whakangoatia 2h LCso: 75000mg/m3. He kino te matū ki te taiao, ka pokea te tinana wai me te hau, ka whakaemi koiora i roto i nga mekameka kai nui mo te tangata, ina koa i nga ika. Ka taea e te Heptane te whanoke, te nausea, te korekore, te haere ohorere, tae atu ki te ngaro o te mahara me te porangi. Rokiroki i roto i te whare putunga hauhautanga, whai hau. Tino whakaraerae ki te ahi. Kia matara atu i te ahi me nga puna wera. Ko te mahana o te whare putunga kaua e neke ake i te 30°C. Tiaki i te ra tika. Kia hiritia te ipu. Me penapena motuhake mai i te kaihoko whakahaora.
