Product Properties:
1.Ethyl acetate iri nyore hydrolysed, uyewo zvishoma nezvishoma hydrolysed kuti iite acetic acid uye ethanol muhupo hwemvura panzvimbo yekupisa.Kuwedzerwa kwehuwandu hweasidhi kana chigadziko kunogona kusimudzira maitiro ehydrolysis.Ethyl acetate inogona zvakare kuita alcoholysis, ammonolysis, ester exchange, kuderedza uye zvimwe zvinowanzoitika zvegeneral esters.Iyo inoputika pachayo muhupo hwesimbi ye sodium kuti iite 3-hydroxy-2-butanone kana ethyl acetoacetate;inopindirana neGrignard's reagent kuti igadzire ketone, uye imwezve mhinduro inopa doro repamusoro.Ethyl acetate inenge yakagadzikana pakupisa uye inoramba isingachinji kana ichipisa pa290 ° C kwemaawa 8-10.Inoora kuita ethylene uye acetic acid kana yapfuura nepaipi-inopisa yesimbi pombi, ichipinda muhydrogen, carbon monoxide, carbon dioxide, acetone uye ethylene kuburikidza ne zinc poda inopisa kusvika 300 ~ 350 ° C, uye mumvura, ethylene, carbon dioxide uye acetone kuburikidza. dehydrated aluminum oxide pa 360°C.Ethyl acetate inoora ne ultraviolet irradiation kugadzira 55 per cent carbon monoxide, 14 per cent carbon dioxide uye 31 per cent hydrogen kana methane, ari magasi anopfuta.Kuita ne ozone kunogadzira acetaldehyde uye acetic acid.Gaseous hydrogen halides inobata ne ethyl acetate kuumba ethyl halide uye acetic acid.Hydrogen iodide ndiyo inonyanya kushanda, ukuwo hydrogen chloride inoda kudzvanywa kuti iore patembiricha yekamuri, uye inopisa kusvika 150°C nephosphorus pentachloride kuita chloroethane neacetyl chloride.Ethyl acetate inoumba akasiyana crystalline complexes ane simbi munyu.Aya macomplexes anonyungudika muanhydrous ethanol asi kwete mu ethyl acetate uye ari nyore hydrolysed mumvura.
2.Kugadzikana: Kugadzikana
3.Zvinhu zvinorambidzwa: Mishonga yakasimba, alkali, acids
4.Polymerization ngozi: Kwete-polymerisation
Product Application:
Inogona kushandiswa kunyungudutsa nitrocellulose, inki yekudhinda, mafuta uye girisi, nezvimwewo. Inogonawo kushandiswa sechinhu chakasvibiswa chependi, ganda rekugadzira, zvigadzirwa zvepurasitiki, dhayi, mishonga uye zvinonhuwira, nezvimwewo.
Chigadzirwa Chekuchengetedza Notes:
1.Chengetedza munzvimbo inotonhorera, ine mhepo yekuchengetera mhepo.
2.Gara kure nemoto uye kupisa sosi.
3.Kupisa kwekuchengetedza hakufaniri kudarika37°C.
4.Chengetedza mudziyo wakavharwa.
5.Inofanira kuchengetwa zvakasiyana kubva kune oxidising agents,maasidhi uye alkalis,uye haifaniri kumbosanganiswa.
6.Shandisa kuputika-kuvhenekera uye zvivako zvemhepo.
7.Kurambidza kushandiswa kwemichina yemagetsi uye zvishandiso zviri nyore kugadzira mazhenje.
8.Nzvimbo yekuchengetera inofanirwa kuve neyakavuza yekurumidzira kurapwa michina uye yakakodzera pekugara zvinhu.
