4-Methoxybenzyl utywala(CAS#105-13-5)
| Iikhowudi zoMngcipheko | I-R22 – Iyingozi xa iginyiwe R36/37/38 – Ukucaphuka kwamehlo, inkqubo yokuphefumla kunye nolusu. I-R63 – Ingozi enokwenzeka yokwenzakala kumntwana ongekazalwa I-R62 – Umngcipheko onokubakho wokuphazamiseka kokuchuma I-R41 – Umngcipheko womonakalo omkhulu emehlweni I-R37/38 – Iyacaphukisa inkqubo yokuphefumla kunye nolusu. I-R20/21/22 – Iyingozi ngokuphefumla, xa udibana nolusu naxa uginyiwe. |
| Inkcazelo yoKhuseleko | S26 – Xa udibana namehlo, hlambulula ngokukhawuleza ngamanzi amaninzi kwaye ufune iingcebiso zonyango. S36 – Nxiba iimpahla ezifanelekileyo ezikhuselayo. S45 - Kwimeko yengozi okanye ukuba uziva ungaphilanga, funa iingcebiso zonyango ngokukhawuleza (bonisa ileyibhile nanini na kunokwenzeka.) S36/37/39 – Nxiba iimpahla ezifanelekileyo zokukhusela, iiglavu kunye nokukhusela amehlo/ubuso. |

Intshayelelo
I-Methoxybenzyl utywala. Oku kulandelayo sintshayelelo kwiipropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi lokhuseleko lwe-methoxybenzyl alcohol:
Umgangatho:
Imbonakalo: I-Methoxybenzyl utywala lulwelo olungenambala olunokuthi lube nevumba.
Ukunyibilika: Utywala beMethoxybenzyl abunyibiliki kancinci emanzini, kodwa bunyibilika kuninzi lwezinyibilikisi zendalo.
Uzinzo: I-Methoxybenzyl alcohol izinzile kwiqondo lobushushu begumbi, kodwa inokusabela xa idibana nee-oxidants ezinamandla.
Sebenzisa:
I-Methoxybenzyl alcohol ingasetyenziswa njenge-solvent, i-reaction intermediate kunye ne-catalyst stabilizer kwi-organic synthesis.
Isenokusetyenziswa njengesithako kwiziqhumiso kunye neencasa, ukunika iimveliso ivumba elikhethekileyo.
Indlela:
Utywala be-methoxybenzyl bunokulungiswa ngokugqithiswa kwe-methanol kunye ne-benzyl alcohol. Le mpendulo ifuna i-catalyst kunye neemeko ezifanelekileyo zokusabela.
Isenokusabela nge-oxidant nge-benzyl alcohol ukuvelisa i-methoxybenzyl alcohol.
I-benzyl utywala + i-oxidant → i-methoxybenzyl alcohol
Ulwazi ngoKhuseleko:
I-Methoxybenzyl alcohol sisinyibilikisi esiphilayo kwaye kufuneka isetyenziswe ngokuhambelana nezenzo zokhuseleko lwelabhoratri yekhemikhali ngokubanzi.
Inokubangela ukucaphuka kwamehlo kunye nolusu, kwaye iiglasi ezikhuselayo kunye neeglavu kufuneka zinxitywe ngexesha lokuphatha.
Ukuba uphefumle okanye ufakwe ngengozi, funa unyango ngokukhawuleza kwaye unikeze ipakethe okanye ileyibhile kugqirha wakho ukuze ubhekiselele.
