Whakaahuatanga:
He wai mārama te n-Heptane, he tino mura, he pūngāwerewere hoki, he kakara ngawari, he rite ki te penehīni. Ko te paepae kakara he 40-547 ppm; i kōrerotia hoki he 230 ppm. Taumaha ngota = 100.23; Taumaha motuhake (H2O:l) = 0.68; Ira kohua = 98.39C; Ira tio Ira rewa = - 90.6℃; Pēhanga kohu = 40 mmHg i te 25℃; Ira mura =一4℃; Pāmahana mura aunoa = 204℃.285℃. Ngā rohenga pahūtanga: LEL= 1.1%; UEL= 6.7%. Tāututanga Tūponotanga (i runga i te Pūnaha Whakatauranga NFPA-704 M): Hauora 1, Mura 3, Tauhohenga 0. Kāore e wairewa i roto i te wai; wairewa = 0.0003%.

Whakamahinga
He pai mō te HPLC, te ine irahiko, te whakamātautau taiao
Hei paerewa mō te whakamātautau i te patuki o ngā miihini penehīni.
He whakarewa te heptane, he kaihoko whakaiti i te matotoru.
Te Tākai me te Tukunga
137KG/Pahu, kia rite rānei ki ngā whakaritenga a te kiritaki.
Ka taea te tuku mā te moana me te rangi
Te pupuri me te rokiroki
Te roa o te oranga: 24 marama mai i te rā i hangaia ai, i roto i te takai taketake kāore anō kia whakatuwheratia, rongoatia ki te wāhi matao, maroke, ā, kāore e taea te ārai i te rā tika, i te wai rānei.
Whare putunga hauhautanga, Whakamaroke pāmahana iti, Wehea mai i ngā waikura me ngā waikawa.
