Selelekela

Furfuryl joala. Se latelang ke selelekela sa thepa, tšebeliso, mekhoa ea ho lokisa le tlhaiso-leseling ea polokeho ea joala ba furfuryl:

 

Boleng:

Tahi ea Furfuryl ke mokelikeli o se nang 'mala, o monko o monate o nang le botsitso bo tlase.

Tahi ea Furfuryl e qhibiliha ka metsing hape e tsoakana ka lihlapolli tse ngata tsa tlhaho.

 

Sebelisa:

 

Mokhoa:

Hajoale, joala ba furfuryl bo lokisoa haholo ke motsoako oa lik'hemik'hale. E 'ngoe ea mekhoa e sebelisoang hangata ke ho sebelisa hydrogen le furfural bakeng sa hydrogenation boteng ba catalyst.

 

Lintlha tsa Tšireletseho:

Joala ba Furfuryl bo nkuoa bo bolokehile tlas'a maemo a tloaelehileng a ts'ebeliso, empa bo ka baka maikutlo ho batho ba bang.

Qoba ho kopana le joala ba furfuryl mahlong, letlalong le lera la mucous, 'me u hlatsoe ka metsi a mangata haeba ho kopana ho etsahala.

Tahi ea Furfuryl e hloka tlhokomelo e eketsehileng matsohong a bana ho thibela ho kenngoa ka phoso kapa ho ama.
