Nā Waiwai a me ka Paʻa:
1.Very liʻiliʻi loa a me ka hoʻihoʻi wikiwiki ʻana mai ka make ʻana, no laila hiki ke hoʻohana ʻia ma ke ʻano he anesthetic.E hoʻonāukiuki i ka ʻili a me ka mucous membrane.ʻIole ʻōpio makua waha waha LD50: 1.6mL/kg.ea nui i 'ae 'ia ka mana'o o 500×10-6.Pono e hoʻohana i ka pale kinoea, ʻike ʻia ua make koke ʻia mai ke kahua, ka mālama ʻana i nā hōʻailona.ʻO ka liʻiliʻi i loko o ka chloride o ka methane.ʻO ka mahu he anesthetic maikaʻi loa a ʻo ka inhalation o nā mea nui e hoʻoulu ai i ka ʻawaʻawa me ka ʻeha o ka ihu, ke poʻo a me ka luaʻi.ʻO ka lāʻau ʻawaʻawa ke kumu o ka noʻonoʻo, luhi, pau ka ʻai, impahaematopoiesis ired a me ka hoemi ana o ke koko ulaula.ʻO ka methylene chloride wai ke kumu o ka dermatitis ke pili me ka ʻili.Inhalation o 90.5g/m3 mahu i nā iole make i loko o 90 minuke.ʻO 522mg/m3 ka pae o ka paepae olfactory a ʻo 1740mg/m3 ka nui i ʻae ʻia ma ka wahi hana.
2.Stability: Paʻa
3. Nā mea i pāpā ʻia: Alkali metala, aluminika
4.Conditions no ka pale ʻana i ka ʻike: Light, humid ea
5.Polymerisation pilikia: Non-polymerization
Hoʻohana huahana:
1. Ma waho aʻe o ka organik synthesis, ua hoʻohana nui ʻia kēia huahana e like me cellulose acetate film, cellulose triacetate pumping, petroleum dewaxing, solvents i ka hana ʻana o nā aerosols a me nā lāʻau antibiotic, nā huaora, nā pūhui steroidal, a me ka hoʻomaʻemaʻe ʻana i ka lacquer a me ka degreasing a mea wehe kiʻiʻoniʻoni.
2.Hoʻohana i ka palaoa fumigation a me ka refrigeration o haʻahaʻa-press freezers a me ka ea-conditioning.Hoʻohana ʻia ma ke ʻano he mea hoʻoheheʻe kōkua i ka hana ʻana i ka polyether urethane foam a ma ke ʻano he mea puhi no ka extruded polysulfone foam.
3.Hoʻohana e like me ka solvent, extractant a me mutagen.Hoʻohana ʻia i ka noiʻi genetic mea kanu.
4. He mea hoʻoheheʻe maikaʻi ia, he mea hoʻoheheʻe haʻahaʻa haʻahaʻa me ka liʻiliʻi o nā meaʻawaʻawa a me ka non-flammability i waena o nā mea hoʻoheheʻe ʻenehana i hoʻohana mau ʻia, a loaʻa ka solvency maikaʻi no nā resins, paraffins a me nā momona.Hoʻohana nui ʻia e like me ka pena pena, ka petroleum dewaxing solvent, extractant of thermally unstable substance, extractant o lanolin mai ka hulu hipa a me ka aila ʻai mai ka niu, solvent o cellulose triacetate film.Hoʻohana nui ʻia i ka acetate fiber, vinyl chloride fiber manufacturing, hoʻoponopono a me nā mea hoʻopau ahi, refrigerants, urotropine a me nā mea hana ʻē aʻe.
5.Hoʻohana i ka ʻoihana uila.Hoʻohana maʻamau i mea hoʻomaʻemaʻe e wehe i ka ʻaila.
6.Widely hoʻohana e like me ka lapalapa ahi retardant solvent me ka haʻahaʻa hoʻolapalapa wahi.Ma waho aʻe o ka holoi ʻana i nā mea hoʻoheheʻe no nā ʻenekini mokulele, nā mīkini kikoʻī, a me nā mea ʻē aʻe, hiki ke hoʻohana ʻia ma ke ʻano he mea wehe ʻia no nā pena, a hiki ke hui pū ʻia me nā solvents ʻē aʻe e hoʻohana ʻia i nā ʻano holoi ʻenehana.
7.Also hoʻohana e like me ka ethyl ester fiber solvent, niho kūloko anaesthetic, refrigerant a me ke ahi extinguishing agent, etc., he eluent maʻamau no ka chromatographic separation a me extraction separation o ka maʻamau solvents.
8.Hoʻohana e like me ka solvent i ka resin a me ka ʻoihana plastic.
Nā memo mālama huahana:
1. E kūʻai i loko o kahi hale kūʻai ʻoluʻolu.
2. E mālama i ke ahi a me ke kumu wela.
3. E kūʻai ma kahi mahana ʻaʻole iʻoi aku ma mua o 32 ° C a me kahi haʻahaʻa pili ʻaʻole ma mua o 80%.
4. E hoʻopaʻa i ka pahu.
5. Pono e hoʻokaʻawale ʻia mai nā metala alkali a me nā kemika hiki ke ʻai, a ʻaʻole pono e hui pū ʻia.
6. Hoʻopiliʻia me nāʻano kūpono a me ka nui o nā mea hana ahi.
7. Pono e hoʻolako ʻia ka wahi e mālama ai me nā lako lapaʻau ulia pōpilikia a me nā lako hale kūpono.
