Isingeniso
I-Monomethyl subrate, ifomula yamakhemikhali i-C9H18O4, iyinhlanganisela yezinto eziphilayo. Okulandelayo yincazelo yemvelo yayo, ukusetshenziswa, ukulungiswa kanye nolwazi lokuphepha:
Imvelo:
- I-Monomethyl subrate iwuketshezi olungenambala olunephunga elibuthakathaka lezithelo ezingeni lokushisa elilingana negumbi.
-Ukuminyana kwayo kucishe kube ngu-0.97 g/mL, futhi indawo yayo yokubila icishe ibe ngu-220-230°C.
- I-Monomethyl subrate inokuncibilika okuhle futhi ingancibilika kuzincibilikisi eziningi eziphilayo, njengotshwala nama-ether.
Sebenzisa:
- I-Monomethyl subrate ingasetshenziswa ukuhlanganisa ezinye izinto eziphilayo, njengezinambitheka, amakhambi, imithi kanye nodayi.
-Ingasetshenziswa futhi emisebenzini yezimboni njengama-solvents, ama-lubricant nama-plasticizers.
Indlela Yokulungiselela:
-Indlela evamile yokulungiselela ye-Monomethyl subrate iwukusabela kwe-esterification ye-suberic acid ne-methanol. Ukusabela ngokuvamile kwenziwa ngaphansi kwezimo ezine-acidic kusetshenziswa i-acid catalyst efana ne-sulfuric acid noma i-methylating agent efana ne-methylsulfuric acid.
Ulwazi Lokuphepha:
- Ubuthi be-Monomethyl subrate low, kodwa kusadingeka ukuthi unake ukusetshenziswa okuphephile.
-Gwema ukuthinta isikhumba namehlo. Uma kukhona ukuthintana, hlambulula ngokushesha ngamanzi amaningi.
-isetshenziselwa ukugcina izimo ezinhle zokungenisa umoya, gwema ukuhogela umhwamuko wayo.
- I-Monomethyl subrate iyavutha futhi kufanele igcinwe kude nomlilo kanye nezinga lokushisa eliphezulu.
-Isitoreji kufanele sivalwe, endaweni epholile neyomile, kude nomlilo kanye nama-oxidizing agents.
