Isobutanol Pūmau-Teitei: Āwhina Tukatuka Polymer
Whakaahuatanga
| Taonga | Waipiro Isobutyl (IBA) |
| 1. Ngā Mōhiohio Taketake | |
| - Ingoa Matū | Waipiro Isobutyl / 2-Methyl-1-propanol |
| - Tātai Irahiko | C₄H₁₀O / (CH₃)₂CHCH₂OH |
| - Nama CAS | 78-83-1 |
| - Hanganga | He waipiro tuatahi me te mekameka peka (isomer o te n-butanol). |
| 2. Ngā Āhuatanga Ā-tinana | |
| - Āhua me te Kakara | He wai kore tae, he kakara reka, he rite ki te waina. |
| - Te wairewatanga | Ka taea te whakaranu ā-wāhanga ki te wai (~8.5% w/w i te 20°C). Ka taea te whakaranu ki te nuinga o ngā whakarewa waro (ethanol, ether, me ētahi atu). |
| - Te Pūwāhi Kohua | 108°C |
| - Te Wāhi Rewa | -108°C |
| - Te Pūwāhi Ngaro | 28°C (kapu kua kati) – Tawhā haumaru matua. |
| - Te mātotorutanga | ~0.802 karamu/cm³ i te 20°C (mama ake i te wai). |
| - Taupū Whakaata | ~1.395 |
| - Te matotoru | Iti (~3.95 mPa·s i te 20°C). |
| 3. Ngā Āhuatanga Matū | |
| - Te tauhohenga | Waipiro tuatahi noa. Ka pāngia e ngā tauhohenga esterification, oxidation, etherification, me te whakakapinga. |
| - Tauhohenga Matua | Te whakaesteritanga (hei tauira, ki te waikawa acetic hei hanga i te iso-butyl acetate, he whakarewa noa). |
| 4. Haumaru me te Whakahaere (Whakarāpopototanga Whakarōpūtanga GHS) | |
| - Te mura | Wai Mura (Kāwai 3) – Puritia kia matara atu i te wera/ngā mura ahi/ngā mura tuwhera. |
| - Ngā Tūponotanga Hauora | Ka pāngia te kiri me ngā kanohi e te riri nui (Kāwai 2). He kino mēnā ka horomia, ka manawahia rānei. |
| - Rokiroki | Penapena ki te wāhi hauhautanga, hauhautanga pai, kua kati pūmau. Hurihia ngā ipu i te wā e whakawhitihia ana. |
| - Te kore hototahi | Ngā matū waikura kaha, ngā waikawa kaha. |
Ko te Isobutanol (CAS 78-83-1) he waipiro aliphatic kounga teitei, he matū ahumahi tino nui, e whakaatu ana i te wai mārama, kore tae me te kakara waipiro ngawari, āhua motuhake. E whakanuia ana mō ōna āhuatanga hydrophilic-lipophilic taurite me te tauhohenga matū pumau, ka mahi te isobutanol hei rauemi matua maha-mahi e tutuki ana i ngā paearu kounga pakari o te tukatuka matū me te hanganga hou.
E whakamahia whānuitia ana puta noa i ngā pūnaha ahumahi o te ao, ko te isobutanol te tuatahi hei whakarewa tino whai hua mō te whakakōkī kapia, te hanga peita me te tango hinu ahumahi; he takawaenga nui hoki mō te hanga i ngā esters motuhake, ngā plasticizer me ngā rauemi mata rongoā. Ka tautokohia anō e ēnei hua o muri mai ngā rāngai matua pērā i te paninga wāhanga motuka, te hanga kakara whakapaipai, te whakaranu reka kai, te hanga tāpiri wahie me te hanganga matū ahuwhenua.
Ka whakaratohia e tā mātou hua isobutanol he whānuitanga katoa o ngā whiringa karaehe (karaehe ahumahi, karaehe polymerization me te karaehe rongoā) hei whakatutuki i ngā āhuatanga tono rerekē, me ngā tikanga tirotiro kounga pakari e whakarite ana i ngā taumata paru tino iti me te mahi hua ōrite. Ka whakapau kaha mātou ki te tuku papatipu pumau, te tiwhikete utanga morearea whānui (tae atu ki te MSDS, ngā tuhinga kaipuke UN me ngā pepa whakaaetanga tikanga), me ngā mahere whakahaere ritenga kua arotauhia mō te kawe wai mura. Hei tāpiri, ka tukuna e tā mātou tīma ratonga hangarau whakatapua te tautoko takitahi—pēnei i te tohutohu arotau whakatakotoranga, ngā tikanga rokiroki me te whakahaere, me te aratohu tutuki haumaru—kia nui ake ai tō whai huatanga whakaputa me te haumarutanga whakahaere.
