Ingcaciso yeMveliso:
Igama lesayensi yeoli yombane emhlophe yi-n-heptane, kuba ine-solubility ephezulu yamafutha kunye nokuguquguquka okuphezulu, kwaye inamandla okutshatyalaliswa kwe-decontamination, isoloko isetyenziswa njenge-agent yokucoca kwishishini, kwaye iyikhemikhali esetyenziswa ngokubanzi kwi-hardware, amashishini ombane, okushicilela kunye nokwenza izihlangu.
Isicelo seMveliso:
I-1.Isetyenziswe njenge-reagent yohlalutyo, i-injini ye-petroli yokuqhuma umgangatho wokuvavanya, i-chromatographic reference reference material, i-solvent.Imveliso inokuvuselela indlela yokuphefumula, kwaye ibe nefuthe le-anesthetic ekugxininiseni okuphezulu.Inokutsha, ukuxinwa komda wokwenza umxube oqhumayo emoyeni ngu-1.0-6.0% (v / v).
I-2.Ingasetyenziselwa njenge-solvent ye-extraction yezilwanyana kunye nezityalo zeoli kunye namafutha, i-samente yerubha eyomileyo ngokukhawuleza.Ukunyibilikisa kushishino lwerabha.Ikwasetyenziswa njengokucoca i-solvent kwipeyinti, ivanishi, i-inki eyomisa ngokukhawuleza kunye neshishini lokushicilela.Imveliso ecocekileyo isetyenziswa njengesibaso esiqhelekileyo sokumisela inani le-octane yepetroli.
I-3.Isetyenziswe njengomgangatho kunye ne-solvent yokumisela inombolo ye-octane, kunye ne-organic synthesis kunye nokulungiswa kwee-reagents zovavanyo.
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.
5. Kufuneka igcinwe ngokwahlukileyo kwi-oxidising agents, kwaye akufanele ixutywe.
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.
