Isicelo somkhiqizo:
I-1.I-Ethanol iyi-solvent ebalulekile ye-organic, esetshenziswa kabanzi kwezokwelapha, upende, imikhiqizo yenhlanzeko, izimonyo, uwoyela namafutha nezinye izindlela, ezibalelwa ku-50% wengqikithi yokusetshenziswa kwe-ethanol.I-Ethanol iyi-acetaldehyde, i-ethylene diene, i-ethylamine, i-ethyl acetate, i-acetic acid, i-chloroethane, njll. , izibulala-zinambuzane, njll., enezinhlobo ezingaphezu kuka-300 zemikhiqizo, kodwa manje ukusetshenziswa kwe-ethanol njengengxenye yomkhiqizo wamakhemikhali kuncipha kancane kancane, futhi imikhiqizo eminingi, njenge-acetaldehyde, i-acetic acid, i-ethyl alcohol, ayisasebenzisi i-ethanol njengesithako. impahla eluhlaza, kodwa ethyl utshwala njengoba impahla eluhlaza.Nokho, ukusetshenziswa kwe-ethanol njengengxenye yamakhemikhali kuncipha kancane kancane, futhi imikhiqizo eminingi efana ne-acetaldehyde, i-acetic acid, i-ethyl alcohol ayisasebenzisi i-ethanol njengento eluhlaza, kodwa ithathelwa indawo ezinye izinto zokusetshenziswa.I-ethanol ecwengisiswe ngokukhethekile iyasetshenziswa nasekukhiqizeni iziphuzo.Ngokufanayo ne-methanol, i-ethanol ingasetshenziswa njengomthombo wamandla.Amanye amazwe aseqalile ukusebenzisa i-ethanol iyodwa njengophethiloli wemoto noma ehlanganiswe nophethiloli (10% noma ngaphezulu) ukuze wonge uphethiloli.
I-2.Isetshenziswa njenge-solvent ye-adhesives, i-nitro spray paints, ama-varnishes, izimonyo, iziyinki, izihluthulelo zopende, njll., kanye nempahla eluhlaza yokwenziwa kwezibulala-zinambuzane, imithi, amarabha, amapulasitiki, ama-synthetic fibers, okokuhlanza, njll. , futhi njenge-antifreeze, uphethiloli, isibulala-magciwane nokunye.Embonini ye-microelectronics, esetshenziswa njenge-ejenti yokukhipha amanzi kanye ne-decontamination, ingasetshenziswa ngokuhambisana ne-ejenti yokuhlanza.
3.Isetshenziswa njenge-reagent yokuhlaziya, njenge-solvent.Isetshenziswa futhi embonini yezemithi.
4.Isetshenziswa embonini ye-elekthronikhi, isetshenziswa njenge-ejenti yokukhipha amanzi kanye ne-decontamination kanye nezithako ze-ejenti yokuhlanza.
5.Isetshenziselwa ukuncibilikisa ezinye izithasiselo ze-organic ze-electroplating ezingancibiliki, eziphinde zisetshenziswe njenge-hexavalent chromium enciphisa i-ejenti yokunciphisa kukhemistri yokuhlaziya.
6.Isetshenziswa embonini yewayini, i-organic synthesis, i-disinfection nanjenge-solvent.
Amanothi Okugcina Umkhiqizo:
1.Gcina endaweni epholile, nengena umoya.
2. Gcina kude nomlilo kanye nomthombo wokushisa.
3.Izinga lokushisa lokugcina akufanele lidlule ku-37°C.
4.Gcina isitsha sivaliwe.
5.Kufanele igcinwe ngokuhlukana nama-oxidants, ama-acids, izinsimbi ze-alkali, ama-amine, njll., ungahlanganisi isitoreji.
6.Sebenzisa izibani ezingaqhumi kanye nezindawo zokungenisa umoya.
7.Vimbela ukusetshenziswa kwemishini namathuluzi alula ukwenza izinhlansi.
I-8.Indawo yokugcina kufanele ifakwe imishini yokwelapha izimo eziphuthumayo ezivuzayo kanye nezinto zokukhosela ezifanele.
