Selelekela

Phenol, eo hape e tsejoang e le hydroxybenzene, ke motsoako oa lintho tse phelang. Se latelang ke selelekela sa thepa, tšebeliso, mekhoa ea ho lokisa le tlhaiso-leseling ea polokeho ea phenol:

 

Boleng:

- Ponahalo: Ha e na 'mala ho isa ho e tšoeu ea kristale e tiileng.

- Solubility: E qhibiliha ka metsing le ka bongata ba lihlapolli tsa tlhaho.

- Monko: Ho na le monko o khethehileng oa phenolic.

- Reactivity: Phenol ha e nke lehlakore 'me e ka ba le karabelo ea acid-base, karabelo ea oxidation, le karabelo ea phetisetso le lintho tse ling.

 

Sebelisa:

- Indasteri ea lik'hemik'hale: Phenol e sebelisoa haholo ha ho etsoa lik'hemik'hale tse kang phenolic aldehyde le phenol ketone.

- Li-preservatives: Phenol e ka sebelisoa e le se bolokang patsi, sebolaea likokoana-hloko le fungicide.

- Indasteri ea rabara: e ka sebelisoa e le tlatsetso ea rabara ho ntlafatsa viscosity ea rabara.

 

Mokhoa:

- Mokhoa o tloaelehileng oa ho lokisa phenol ke ka oxidation ea oksijene moeeng. Phenol e ka boela ea lokisoa ke karabelo ea demethylation ea li-catechols.

 

Lintlha tsa Tšireletseho:

- Phenol e na le chefo e itseng 'me e na le phello e halefisang letlalong, mahlo le mokhoa oa ho hema. Hlatsoa ka metsi hang ka mor'a ho pepeseha 'me u batle thuso ea bongaka hang-hang.

- Ho pepeseha ha lintho tse ngata tsa phenol ho ka hlahisa matšoao a chefo, ho kenyelletsa ho tsekela, ho nyekeloa ke pelo, ho hlatsa, joalo-joalo Ho pepeseha ha nako e telele ho ka baka tšenyo sebeteng, liphio le tsamaiso ea methapo e bohareng.

- Nakong ea polokelo le ts'ebeliso, ho hlokahala mehato e nepahetseng ea ts'ireletso joalo ka ho roala liatlana tse sireletsang, likhalase, joalo-joalo. Sebetsa sebakeng se nang le moea o motle.
