二. Kufotokozera
| Zinthu | Zofotokozera |
| Maonekedwe | Zamadzimadzi zowoneka bwino zopanda mtundu |
| Mtundu (APHA) | ≤10 |
| Chiyero | ≥99.9% |

三. Kugwiritsa ntchito
1.Monga zosungunulira wamba,Tetrahydrofuranchimagwiritsidwa ntchito kwambiri zokutira pamwamba, zokutira zoteteza, inki, extractants ndi mankhwala pamwamba pa chikopa yokumba.
2.Tetrahydrofuranndi zofunika zopangira kupanga PTMEG ndi zosungunulira waukulu makampani mankhwala.
四.Katundu
Tetrahydrofuranndi madzi oonekera opanda mtundu okhala ndi fungo la etha. Zimasakanikirana ndi madzi, mowa, acetone, benzene, ester, ether ndi hydrocarbon.
五.Kugwira ndi Kusunga
1. Njira zodzitetezera kuti musagwire bwino
Pewani kukhudzana ndi khungu ndi maso. Pewani kupuma mpweya kapena nkhungu.
Khalani kutali ndi magwero akuyatsira - Osasuta. Tengani njira zopewera kukulitsa kwa electrostatic
kulipira.
2. Zinthu zosungirako zotetezeka, kuphatikiza zosagwirizana
Sungani pamalo ozizira. Sungani chidebe chotsekedwa mwamphamvu pamalo owuma komanso mpweya wabwino. Zotengera zomwe zatsegulidwa ziyenera kutsekedwa bwino ndikusungidwa kuti zisatayike.
Zotsalira zouma ndizophulika. Sungani pansi pa gasi wopanda pake. Yesani mapangidwe a peroxide nthawi ndi nthawi musanayambe distillation.
Kalasi yosungira (TRGS 510): Zakumwa zoyaka moto
