izidingo

Izimfuneko zekhwalithi ye-2-naphthol zizohambisana nezimfuneko ezikuThebula 1.

Isithombe

Indlela yokuhlola ye

Ukunqunywa komswakama

Ngokusho kwe-3.4″ Karl Fischer Method kanye ne-Karl Fischer Modification Method “ku-GB/T 2386-2006.

Isampula yevolumu ye-2-naphthol ingu-2g.

Umehluko phakathi kwemiphumela yokulinganisa emibili akufanele ube ngaphezu kuka-0.02% (ingxenye yobuningi), futhi isilinganiso se-arithmetic semiphumela emibili yokulinganisa kufanele sithathwe njengomphumela wokulinganisa.

Intengo nekhwalithi yomkhiqizo iyakhuluma,
Uma ucabanga ukuthi intengo iphezulu, thumela isampula ukuze uhlole ikhwalithi. I-#sampuli #imahhala.
Faka i-oda kusenesikhathi bese ubuya kusenesikhathi. Intengo yamanje ihlale ikhuphuka. Uma usangabaza, woza kimi ukuze ngikubuze futhi uxoxe.
I-2- #Naphthol, ephansi kunentengo #yemakethe, ingasetshenziswa ekukhiqizeni #ekhemisi kanye #nodayi. Amathani okugcina angama-20 ezimpahla ezinenani elihle azothengiswa aphele futhi intengo izokhuphuka.
Isetshenziswa ekulungiseni i- #Tobias acid, #J acid, 2.3-acid, kanye nasekulungiseni #anti-aging agent D, anti-aging agent #DNP kanye ne-anti-aging agent, #organic pigment kanye #bactericide .
