Intshayelelo

I-Ligustral (ekwabizwa ngokuba yi-xanthrin) yi-organic compound. Oku kulandelayo kukwazisa kwiipropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi lokhuseleko lwe-ligustral:

 

Umgangatho:

-I-Ligustrum yikristale engenambala ukuya kumthubi kunye nevumba elimnandi elimnandi kubushushu begumbi.

- Iyanyibilika kwizinyibilikisi ze-organic ezifana ne-ethanol, i-ethers kunye ne-ester solvents kwiqondo lobushushu begumbi, kodwa phantse ayinyibiliki emanzini.

-I-Ligustral inokuguquka okuphezulu kwaye kulula ukuzithoba.

 

Sebenzisa:

- Isetyenziswa kakhulu kushishino lwencasa njengesithako sencasa yesityalo sendalo esinokunika iipropati ezinevumba elimnandi kwiimveliso.

 

Indlela:

- I-Ligustrum inokulungiswa nge-oxidation ye-ligustrum (ephuma kwisiqhamo se-ligustrum). I-Ligustrum ifunyenwe ngokuphendula phantsi kweemeko ezifanelekileyo kunye ne-oxidizing agent efana ne-acidic potassium permanganate okanye i-oxygen.

 

Ulwazi ngoKhuseleko:

- ILigustaldehyde ithathwa njengekhompawundi ekhuselekileyo, kodwa isafuna ukhathalelo olufanelekileyo.

-Iyinto ecaphukisayo enokubangela ukucaphuka kwamehlo, ulusu, kunye nenkqubo yokuphefumla.

- Ukuvezwa kwi-ligustrum kufuneka kuphetshwe ngexesha lokusebenza kwaye umoya olungileyo kufuneka uqinisekiswe.

- Xa uphethe i-ligustrum, nxiba izixhobo ezifanelekileyo zokuzikhusela ezinjengeeglavu, iiglasi zokhuselo, kunye nemaski.
