4-methoxy-α,α-dimethylbenzyl joala, e tsejoang hape e le 4-methoxy-α,α-dimethylbenzyl joala, ke motsoako oa lintho tse phelang. Se latelang ke selelekela sa tse ling tsa thepa ea eona, litšebeliso, mekhoa le litaba tsa polokeho:Tlhaho:
- Foromo ea lik'hemik'hale: C11H16O2
- Boima ba molek'hule: 180.24g / mol
-Ponahalo: E tšoeu kristale kapa phofo e tiileng
- Sebaka se qhibilihang: 61-64°C
-Boemo bo Belang: 104-106°C(0.3 mmHg)
- Boima: 1.035g/cm3
-Solubility: E qhibiliha ka har'a ethanol, acetone, carbon disulfide le metsoako e meng ea tlhaho.

Sebelisa:
- 4-methoxy-α,α-dimethylbenzyl tai e atisa ho sebelisoa e le li-intermediate ka har'a motsoako oa lintho tse phelang 'me li ka sebelisoa ho etsa lik'hemik'hale le chefo e bolaeang likokoanyana.
-E ka boela ea sebelisoa e le motsoako oa monko o monate ho fa sehlahisoa monko o khethehileng.

Mokhoa oa ho itokisa:
Mokhoa o tloaelehileng oa ho kopanya o lokiselitsoe ke alkylation ea toluene le methoxycarbonylation tlas'a maemo a fokolang. Mehato e khethehileng e ka ba ka tsela e latelang:
1. ka methyl chloride kapa dimethylformamide, ho sebelisa aluminium chloride e le mohloli oa toluene alkylation reaction, synthesis ea benzyl chloride. Karabelo hangata e etsoa ka mocheso o tlase.
2. benzyl chloride e entsoeng ka maiketsetso le methanol e sebetsanoa, 'me lithium aluminium cyanide e sebelisoa e le mohloli oa methoxycarbonylation ho hlahisa joala ea 4-methoxy-α,α-dimethylbenzyl.

Lintlha tsa Tšireletseho:
4-methoxy-α, α-dimethylbenzyl joala bo chefo bo tlase, empa mehato e latelang ea polokeho e lokela ho eloa hloko:
- Qoba ho hema, ho kopana le letlalo le ho mo metsa.
-Apara liatlana tse sireletsang, likhalase tsa tšireletso le mask a sireletsang nakong ea ts'ebetso.
-Nakong ea ts'ebetso, e lokela ho etsoa sebakeng se nang le moea o motle.
-Ha u kopana le letlalo kapa mahlo, hlatsoa hang-hang ka metsi a mangata 'me u batle thuso ea bongaka.
- Qoba ho kopana le lintho tse joalo ka li-oxidants tse matla.

Ka kopo hlokomela hore lintlha tsena ke tsa litšupiso feela. Mekhoa ea ts'ireletso ea laboratori le melaoana e nepahetseng e lokela ho lateloa ha ho sebetsoa kapa ho sebelisoa motsoako ona.
