Boleng:

- Ponahalo: E tiileng ea kristale e se nang 'mala;

- Ha e qhibilihe ka metsing 'me e qhibiliha haholoanyane ka har'a li-solvents tse kang li-ethers le joala;

- E na le monko o monate.

 

Sebelisa:

- 3,5-Dimethylbenzoic acid ke karolo ea bohlokoa ea bohareng ba motsoako oa lintho tse phelang 'me hangata e sebelisoa ha ho etsoa metsoako e meng ea lintho tse phelang;

- E ka sebelisoa e le lisebelisoa tse tala bakeng sa li-resin tsa polyester le likoahelo, li-plastiki le li-additives tsa rabara;

 

Mokhoa:

- Mokhoa oa ho lokisa oa 3,5-dimethylbenzoic acid o ka fumanoa ka karabelo ea benzaldehyde ka dimethyl sulfide;

- Karabelo hangata e etsoa tlas'a maemo a acidic, 'me li-catalyst tse nang le asiti tse kang hydrochloric acid li ka sebelisoa;

- Kamora karabelo, sehlahisoa se hloekileng se fumanoa ka kristale kapa ho ntšoa.

 

Lintlha tsa Tšireletseho:

- Motsoako o hloka ho sebelisoa ho latela liprothokholo tse nepahetseng tsa laboratori;

- E ka baka ho teneha mahlong, letlalong le tsamaisong ea ho hema;

- Apara lisebelisoa tsa ho itšireletsa, joalo ka liatlana tsa lab le likhalase, 'me u netefatse hore ho na le moea o motle ha o sebelisoa;

- Qoba ho kopana le li-oxidizing tse matla le li-acid tse matla;

- Boloka e omme, e tiisitsoe ka thata, 'me u qobe ho kopana le moea, mongobo le mollo.

Ha u sebelisa 3,5-dimethylbenzoic acid kapa lik'hemik'hale leha e le life, ke habohlokoa ho latela mekhoa e nepahetseng ea ho sebetsana le lik'hemik'hale le mekhoa e sireletsehileng.
