三. Isicelo

1.Njenge-solvent evamile,I-Tetrahydrofuranisetshenziswa kabanzi ekugqokeni okungaphezulu, ezingxenyeni ezivikelayo, oyinki, ekukhishweni nasekuphathweni kwangaphezulu kwesikhumba sokwenziwa.

2.I-Tetrahydrofuraniyingxenye ebalulekile yokukhiqizwa kwe-PTMEG kanye ne-solvent eyinhloko embonini yezemithi.

 

四.Impahla

I-Tetrahydrofuraniwuketshezi olukhanyayo olungenambala olunephunga le-ether. Ixubene namanzi, utshwala, i-acetone, i-benzene, i-ester, i-ether ne-hydrocarbon.

 

五.Ukuphatha kanye Nesitoreji

1. Izinyathelo zokuphepha zokuphatha ngendlela ephephile

Gwema ukuthinta isikhumba namehlo. Gwema ukuhogela umhwamuko noma inkungu.

Ziqhelelanise nemithombo yokuthungela - Akubhenywa. Thatha izinyathelo zokuvimbela ukwakheka kwe-electrostatic

khokhisa.

2. Imibandela yokugcina okuphephile, okuhlanganisa noma yikuphi ukungahambisani

Gcina endaweni epholile. Gcina isitsha sivalwe ngokuqinile endaweni eyomile futhi enomoya omuhle. Iziqukathi ezivulwayo kufanele zivalwe kabusha ngokucophelela futhi zigcinwe zimile ukuze zingavuzi.

Izinsalela ezomile ziyaqhuma. Gcina ngaphansi kwegesi engasebenzi. Hlola ukwakheka kwe-peroxide ngezikhathi ezithile nangaphambi kokukhishwa kwe-distillation.

Isigaba sesitoreji (TRGS 510): Uketshezi oluvuthayo
