Nā waiwai huahana:
1. Ethyl acetate ua maʻalahi hydrolysed, a no hoi lohi hydrolysed e hana acetic waikawa a me ka ethanol i mua o ka wai ma lumi wela.Hiki i ka hoʻohui ʻana i ka nui o ka waikawa a i ʻole ke kumu ke hoʻoikaika i ka hopena hydrolysis.Hiki i ka Ethyl acetate ke komo i ka alcoholysis, ammonolysis, ester exchange, ho'ēmi a me nā hopena maʻamau o nā esters maʻamau.Hoʻopili ʻo ia iā ia iho i mua o ka metala sodium e hana i ka 3-hydroxy-2-butanone a i ʻole ethyl acetoacetate;hana ia me ka Grignard's reagent e hana ketone, a hāʻawi ka hopena hou i ka waiʻona kiʻekiʻe.ʻO ka Ethyl acetate ka mea paʻa i ka wela a hoʻololiʻole i ka wā i wela ai ma 290 ° C no nā hola 8-10.Hoʻoheheʻe ia i ka ethylene a me ka acetic acid i ka wā e hele ai i loko o ka paipu hao ʻulaʻula, i loko o ka hydrogen, carbon monoxide, carbon dioxide, acetone a me ka ethylene ma o ka pauka zinc i hoʻomehana ʻia i 300 ~ 350 ° C, a i loko o ka wai, ethylene, carbon dioxide a me acetone ma o alumini oxide maloo ma 360°C.Hoʻoheheʻe ʻia ka Ethyl acetate e ka irradiation ultraviolet e hana i 55 pākēneka kalapona monoxide, 14 pākēneka kalapona a me 31 pākēneka hydrogen a i ʻole methane, he mau kinoea hiki ke ahi.ʻO ka hopena me ka ozone e hoʻopuka i ka acetaldehyde a me ka acetic acid.Hoʻopili ka hydrogen halides me ka ethyl acetate e hana i ka ethyl halide a me ka acetic acid.ʻO ka hydrogen iodide ka mea hoʻoikaika loa, aʻo ka hydrogen chloride e koi i ke kaomi e decompose ma ka lumi wela, a ua wela i 150 ° C me ka phosphorus pentachloride e hana i ka chloroethane a me ka acetyl chloride.Hoʻokumu ʻo Ethyl acetate i nā ʻano paʻakikī crystalline me nā paʻakai metala.Hiki ke hoʻoheheʻe ʻia kēia mau mea paʻakikī i ka ethanol anhydrous akā ʻaʻole i ka ethyl acetate a ua maʻalahi ka hydrolysed i ka wai.
2.Stability: Paʻa
3. Nā mea i pāpā ʻia: ʻO nā oxidants ikaika, alkalis, acids
4.Polymerisation pilikia: Non-polymerization
Hoʻohana huahana:
Hiki ke hoʻohana ʻia e hoʻopau i ka nitrocellulose, ka inika paʻi, ka aila a me ka momona, a me nā mea ʻē aʻe.
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.ʻAʻole pono eʻoi aku ka mahana o ka mālamaʻana37°C.
4. E hoʻopaʻa i ka pahu.
5. Pono e mālama kaʻawale ʻia mai nā mea oxidizing,nā waikawa a me nā alkali,aole pono e huikau.
6.E hoʻohana i nā kukui pahū-hōʻoia a me nā pono ea.
7. Hoʻopaʻa i ka hoʻohana ʻana i nā mea hana mīkini a me nā mea hana maʻalahi e hoʻohua i nā huna huna.
8.Pono e hoʻolako ʻia ka wahi e mālama ai me nā lako lapaʻau ulia pōpilikia a me nā lako hale kūpono.
