5-Methyl-1 2 4-Oxadiazole-3-Carboxylic Acid(CAS# 19703-92-5)

ʻO 5-Methyl-1,2, Acid, i ʻike ʻia ʻo MMT (Methylcyclopropene), he mea hoʻohuihui. Eia ka wehewehe ʻana o kona ʻano, hoʻohana, hoʻomākaukau a me ka ʻike palekana: Nature:
- He wai waihoʻoluʻu ʻole ka MMT me kahi ʻala ʻala.
-He haʻahaʻa haʻahaʻa a hiki ke hoʻoheheʻe ʻia i nā mea hoʻoheheʻe organik e like me ka ethanol a me ka methanol.
- He pūhui paʻa ka MMT, akā e hoʻoheheʻe ʻia i ka wela kiʻekiʻe a ma lalo o ka lā.

E hoʻohana:
- Hoʻohana nui ʻia ʻo MMT ma ke ʻano he mea hoʻoponopono ulu mea kanu, a ʻo kāna hana nui ke kāohi i ka ethylene synthesis o nā mea kanu, a laila e hoʻopaneʻe i ke kaʻina hana a me ka ʻelemakule o nā mea kanu.
-ma muli o kona mau hiʻohiʻona o ka lōʻihi o ka ulu ʻana o ka mea kanu, he noi koʻikoʻi ka MMT i ke kaʻina o ka mālama ʻana a me ka lawe ʻana i nā huaʻai a me nā mea kanu.

Hanana:
Loaʻa ke ʻano hoʻomākaukau maʻamau o-MMT ma ka hana ʻana i ka Oxadiazole me ka methanol. ʻO nā ʻanuʻu kikoʻī e pili ana i ka hoʻomehana ʻana i ka hui ʻana, ka distillation, a me ka hoʻomaʻemaʻe.

ʻIke palekana:
- Ua palekana ʻo MMT i ka hoʻohana ʻana ma lalo o nā kūlana maʻamau, akā pono e hoʻolohe ʻia nā ʻōlelo aʻe:
-E pale i ka inhalation a me ka pili o ka ili ma muli o kona pilau. ʻO ka hoʻohana kūpono ʻana i nā mea pale pilikino, e like me nā mīkina lima, nā maka, nā maka maka, a pēlā aku.
- Pono e mālama ʻia ka MMT mai ke ahi a me ka wela kiʻekiʻe e pale ai i kona decomposition a i ʻole ka puhi ʻana.
-I ka lawelawe ʻana a mālama ʻana paha i ka MMT, pono e hahai ʻia nā kaʻina hana palekana kūpono a me nā ʻenehana hana e hōʻoia i ka palekana pilikino a me ka palekana o ke kaiapuni. I ka wā e pono ai, pono e hana ʻia ma kahi wahi i hoʻoluʻu maikaʻi ʻia.
