Mea Hana Kumukūʻai Maikaʻi Triphenylmethane ʻekolu isocyanate (solution ethyl acetate) CAS: 141-78-6 Brand: Desmodur_RE

1. Hoʻohana ʻia ʻo Ethyl acetate ma ke ʻano he mea hoʻoheheʻe no nā varnish, lacquers, a me nitrocellulose; ma ke ʻano he ʻono hua hana; i ka hoʻomaʻemaʻe ʻana i nā lole; a i ka hana ʻana i ka silika hana a me ka ʻili, nā mea ʻala, a me nā kiʻiʻoniʻoni kiʻi a me nā pā (Merck 1996). Hoʻohana nui ʻia ʻo Ethyl Acetate ma ke ʻano he mea hoʻoheheʻe i nā hopena organik. Nā mea haumia o ke kaiapuni; Nā mea haumia meaʻai.

2. Hoʻohana nui ʻia ʻo Ethyl acetate ma ke ʻano he mea hoʻoheheʻe a me ka mea hoʻoheheʻe, makemake nui ʻia ma muli o kona kumukūʻai haʻahaʻa, haʻahaʻa ka ʻawaʻawa, a me ka ʻala ʻoluʻolu. No ka laʻana, hoʻohana pinepine ʻia ia e hoʻomaʻemaʻe i nā papa kaapuni a ma kekahi mau mea wehe varnish kui (hoʻohana pū ʻia ka acetone a me ka acetonitrile). Hoʻopau ʻia nā pīni kofe a me nā lau kī me kēia mea hoʻoheheʻe. Hoʻohana ʻia hoʻi ia i nā pena ma ke ʻano he mea hoʻoulu a mea paʻakikī paha. [citation needed] Aia ka Ethyl acetate i loko o nā mea ʻono, nā mea ʻala, a me nā huaʻai. I loko o nā mea ʻala, e mahu koke ia, e waiho ana i ke ʻala o ka mea ʻala ma ka ʻili.
3 – 1 - Nā hoʻohana ʻana i ka hale hana
I loko o ka hale hana hoʻokolohua, hoʻohana pinepine ʻia nā hui ʻana i loaʻa ka ethyl acetate i ka chromatography kolamu a me nā unuhi. ʻAʻole koho pinepine ʻia ka Ethyl acetate ma ke ʻano he mea hoʻoheheʻe hopena no ka mea he maʻalahi ia i ka hydrolysis a me ka trans esterification.
3 – 2 - Ka hanana ʻana i nā waina
ʻO Ethyl acetate ka ester maʻamau i ka waina, ʻo ia ka huahana o ka waikawa organik volatile maʻamau - acetic acid, a me ka ethyl alcohol i hana ʻia i ka wā o ka fermentation. ʻOi aku ka ʻala o ka ethyl acetate i nā waina ʻōpio a kōkua i ka ʻike maʻamau o ka "hua" i loko o ka waina.
3 – 3 - Mea pepehi kanaka ʻino
Ma ke kahua o ka entomology, he mea hoʻomake asphyxiant kūpono ka ethyl acetate no ka hoʻohana ʻana i ka hōʻiliʻili ʻana a me ke aʻo ʻana i nā pepeke. I loko o kahi ipu pepehi kanaka i hoʻopiha ʻia me ka ethyl acetate, e pepehi koke nā mahu i ka pepeke i hōʻiliʻili ʻia (ʻo ka maʻamau he pākeke) me ka ʻole o ka luku ʻana. No ka mea, ʻaʻole ia he hygroscopic, mālama pū ka ethyl acetate i ka pepeke i ka palupalu e ʻae i ke kau pono ʻana i kūpono no kahi hōʻiliʻili.

3. Kōkua lāʻau lapaʻau (ʻono); nā ʻano hua hana; mea hoʻoheheʻe no ka nitrocellulose, nā varnish, nā lacquers, a me nā dopes mokulele; hana ʻana i ka pauka uahi ʻole, ka ʻili hana, nā kiʻiʻoniʻoni a me nā pā kiʻi, ka silika hana, nā mea ʻala; nā lole hoʻomaʻemaʻe, a pēlā aku.
