Idatha ye-Toxicological
Ubuthi obuyingozi:

I-Oral LD50: 783mg/kg (ingulube ye-Guinea)

800 mg/kg(mus)

832 mg/kg(igundane)

Imiphumela ecasulayo eyinhloko:

Esikhumbeni: Ukucunula esikhunjeni kanye nolwelwesi lwamafinyila.

Ngaphezu kwamehlo: umphumela wokucasuka.

Ukuzwela: Ayikho imiphumela eyaziwayo yokuzwela.

Idatha yemvelo
Inothi lengubo

Ileveli yengozi yamanzi 1 (Umthethonqubo waseJalimane) (ukuzihlola ngokwakho ngohlu) Le nto iyingozi kancane emanzini.

Ungavumeli inani elingaxutshiwe noma inani elikhulu lomkhiqizo ukuthintana namanzi angaphansi komhlaba, amapayipi amanzi noma amasistimu okukhuculula indle.

Ungakhiphi okokusebenza endaweni ezungezile ngaphandle kwemvume kahulumeni.

Imvelo nokuzinza
Inobuthi obusesilinganisweni, iyacasula isikhumba nolwelwesi lwamafinyila.Umjovo wegundane ongaphansi kwesikhumba LD50:376mg/kg.Imishini yokusabela kufanele ingangeni moya, futhi i-carboxylation reactor kufanele ihlangabezane nezindinganiso zokucindezela.Abasebenzi kufanele bagqoke imaski yokuzivikela nezinye izinto zokuzivikela, futhi balondoloze umoya omuhle endaweni yokusebenzela.

Indlela yokugcina
Lo mkhiqizo kufanele uvalwe futhi ugcinwe kude nokukhanya.

Sebenzisa
Udayi uphakathi.Isetshenziselwa ukwenza iNaphthol AS nezinye izinhlobo zeNaphthol, njengeNaphthol AS-BO, AS-RL, AS-E, AS-D, AS-VL, AS-BS, AS-OL, njll. Ingasetshenziswa futhi khiqiza i-Light Fast Brilliant Red BBC, Light Fast Red BBN, Rubber Red LG, Pigment Brilliant Red 6B, Lithol Red BK.Ibuye isetshenziswe njengesixazululo se-pharmaceutical intermediates.esolve
Ngemuva kokuthi i-β-naphthol kanye ne-sodium hydroxide kwakheka usawoti, ukufudumeza nokuwohloka kuphelelwa amanzi, kanti usawoti we-anhydrous β-naphthol otholakala ugaywa nge-carbon dioxide ukuze ukhiqize usawoti we-2,3 acid disodium, obese ugaywa nge-asidi eyi-sulfuric ukuze uthole usawoti ophelile. umkhiqizo.
