Intshayelelo
I-P-cresol acetate, eyaziwa ngokuba yi-ethoxybenzoate, yi-organic compound. Oku kulandelayo kukwazisa kwiipropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi lokhuseleko lwe-acetic acid p-cresol ester:
Umgangatho:
p-cresol acetate lulwelo olungenambala nevumba elimnandi. Ikhompawundi iyanyibilika kwizinyibilikisi eziphilayo ezifana ne-ethanol kunye ne-ethers, kodwa kunqabile emanzini.
Sebenzisa:
I-p-cresol acetate ineendlela ezahlukeneyo zokusetyenziswa kwishishini. Sisinyibilikisi esiqhelekileyo semizi-mveliso esinokusetyenziswa kwizinto zokugquma, izinto zokuncamathelisa, iintlaka, kunye nezicoci. Isenokusetyenziswa njengento yokulungisa iziqholo kunye ne-musks, evumela incasa kunye neziqholo ukuba zihlale ixesha elide.
Indlela:
Ukulungiswa kwe-p-cresol acetate kunokwenziwa nge-transesterification. Indlela eqhelekileyo kukufudumala nokuphendula i-p-cresol kunye ne-acetic anhydride phambi kwe-acid catalyst ukuvelisa i-p-cresol acetate kunye ne-acetic acid.
Ulwazi ngoKhuseleko:
I-acetic acid inetyhefu kwaye iyacaphukisa kwi-cresol ester. Xa usebenzisa okanye usebenza, kufuneka kuthathelwe ingqalelo ukukhusela ulusu kunye namehlo kwaye ugweme ukudibana ngokuthe ngqo. Ukuba utyiwe okanye urholile, funa unyango ngokukhawuleza. Kufuneka igcinwe kwindawo epholileyo, enomoya kunye neyomileyo, kude nomlilo kunye ne-oxidizers, ukuqinisekisa ukusetyenziswa ngokukhuselekileyo.
