Selelekela

P-cresol acetate, eo hape e tsejoang e le ethoxybenzoate, ke motsoako oa lintho tse phelang. Se latelang ke selelekela sa thepa, ts'ebeliso, mekhoa ea ho lokisa le tlhaiso-leseling ea polokeho ea acetic acid p-cresol ester:

 

Boleng:

p-cresol acetate ke mokelikeli o se nang 'mala o monko o monate. Motsoako o qhibiliha ka har'a metsoako ea tlhaho e kang ethanol le ethers, empa hangata ha e le metsing.

 

Sebelisa:

p-cresol acetate e na le lisebelisoa tse fapaneng indastering. Ke motsoako o tloaelehileng oa liindasteri o ka sebelisoang ho koahela, likhomaretsi, li-resin le lihloekisi. E ka boela ea sebelisoa e le ntho e lokisang monko o monate le li-musks, e lumellang litatso le litlolo hore li tšoarelle nako e telele.

 

Mokhoa:

Ho lokisoa ha p-cresol acetate ho ka etsoa ka transesterification. Mokhoa o tloaelehileng ke ho futhumatsa le ho itšoara ka p-cresol ka acetic anhydride ka pel'a motsoako oa acid ho hlahisa p-cresol acetate le acetic acid.
