Isicelo seMveliso:
I-1.I-Ethanol i-solvent ebalulekileyo yezinto eziphilayo, esetyenziswa ngokubanzi kwiyeza, ipeyinti, iimveliso zococeko, izimonyo, ioli kunye negrisi kunye nezinye iindlela, zibalelwa malunga ne-50% yokusetyenziswa okupheleleyo kwe-ethanol. I-Ethanol yimathiriyeli esisiseko ebalulekileyo yeekhemikhali, esetyenziswa ekwenzeni i-acetaldehyde, i-ethylene diene, i-ethylamine, i-ethyl acetate, i-acetic acid, i-chloroethane, njl. , amayeza okubulala izitshabalalisi, njalo njalo, aneentlobo ezingaphezu kwama-300 zeemveliso, kodwa ngoku ukusetyenziswa kwe-ethanol njengemveliso yemichiza ephakathi kuyancipha ngokuthe ngcembe, kwaye iimveliso ezininzi, njenge-acetaldehyde, i-acetic acid, i-ethyl alcohol, azisasebenzisi i-ethanol njenge impahla ekrwada, kodwa utywala ethyl njengento ekrwada. Nangona kunjalo, ukusetyenziswa kwe-ethanol njengemichiza ephakathi kuyancipha ngokuthe ngcembe, kwaye iimveliso ezininzi ezifana ne-acetaldehyde, i-acetic acid, i-ethyl alcohol ayisasebenzisi i-ethanol njengento ekrwada, kodwa ithathelwa indawo ngezinye izinto eziluhlaza. I-ethanol esulungekisiweyo ngokukodwa iyasetyenziswa ekwenzeni iziselo. Ngokufana ne-methanol, i-ethanol ingasetyenziswa njengomthombo wamandla. Amanye amazwe aqalise ukusebenzisa i-ethanol yodwa njengamafutha esithuthi okanye edityaniswe kwipetroli (10% okanye ngaphezulu) ukonga ipetroli.
I-2.Isetyenziswe njenge-solvent ye-adhesives, i-nitro spray paints, i-varnishes, izimonyo, ii-inki, iipeyinti zepeyinti, njl., kunye ne-raw material yokwenziwa kwe-pesticides, amayeza, i-rubbers, i-plastiki, i-synthetic fibers, i-detergents, njl. , kwaye njenge-antifreeze, fuel, disinfectant njalo njalo. Kwishishini le-microelectronics, elisetyenziswe njenge-ejenti yokucoca kunye ne-decontamination, ingasetyenziselwa kunye ne-agent ye-degreasing.
I-3.Isetyenziswe njenge-reagent yokuhlalutya, njenge-solvent. Ikwasetyenziswa nakwishishini lamayeza.
I-4.Isetyenziswa kwishishini le-elektroniki, esetyenziswa njenge-ejenti yokucoca kunye ne-decontamination kunye nezithako ze-ejenti yokucoca.
5.Isetyenziselwa ukunyibilikisa ezinye izongezo ze-electroplating ze-organic ezinganyibilikiyo, ezikwasetyenziswa njenge-hexavalent chromium yokunciphisa i-agent kwi-analytical chemistry.
I-6.Isetyenziswa kwishishini lewayini, i-organic synthesis, i-disinfection kunye ne-solvent.
Amanqaku okuGcina iMveliso:
1.Gcina kwindawo epholileyo nengena umoya.
2. Gcina kude nomlilo kunye nomthombo wobushushu.
3.Ubushushu bokugcina akufunekanga budlule kwi-37°C.
4. Gcina isitya sivaliwe.
I-5.Kufuneka igcinwe ngokwahlukileyo kwi-oxidants, i-acids, isinyithi se-alkali, i-amines, njl., musa ukuxuba ukugcinwa.
6.Sebenzisa izibane ezingagqabhukiyo kunye nezixhobo zokungenisa umoya.
7.Vimbela ukusetyenziswa kwezixhobo zoomatshini kunye nezixhobo ekulula ukuvelisa iintlantsi.
8.Indawo yokugcina kufuneka ixhotyiswe ngokuvuza kwezixhobo zonyango olungxamisekileyo kunye nezixhobo ezifanelekileyo zokukhusela.
