Boleng:

Ponahalo: E tiileng ka kristale e se nang mmala kapa e mosehla.

Monko: E na le monko o khethehileng.

Solubility: Ho qhibiliha ka har'a ether le joala, ho qhibiliha hanyenyane metsing.

 

Sebelisa:

Liteko tsa lik'hemik'hale: tse sebelisoang e le lihlapolli le li-intermediate ka har'a motsoako oa metsoako ea tlhaho.

 

Mokhoa:

4-Isopropylphenol e ka lokisoa ka mekhoa e 'meli e latelang:

Mokhoa oa ho fokotsa joala oa Isopropylphenyl acetone: 4-isopropylphenol e fumanoa ka ho fokotsa joala ea isopropylphenyl acetone ka hydrogen ka pel'a mokelikeli.
