Acetonitrile: Piny maber man piny ma konyo pi yubu piny ma kwo
Kabedo madongo mi tic
I lembe mi kemikol, acetonitrile ubedo piny ma jutiyo kudu pol kare pi ngiyo piny ma tiyo maber (HPLC) man jamb tiyo ku yamu (GC). Etiye ku solubility maber man viscosity ma nok, ecopo ketho piny matung tung ma kwo man ma kwo ngo pi miyo adwogi maleng. Acetonitrile de jutiyu kudu pi yiko piny ma jutiyo kudu pi pimo, mi neno nia lembe ma jutiyo kudu utiye atira man ma gen.
I yik pa piny makwo, acetonitrile ubedo piny ma pire tek man ma tiyo ikind piny. Ecopu nyayu piny matung tung ma kwo, ma mio kabedo maber pi timo pa kemikol. Ku lapor, i yik pa piny moko ma jutiyo kudu pi yath man piny ma nyayu nguce, acetonitrile copo tiyo calu piny ma nyayu ngwec. Mi medo, acetonitrile copo timo tic i timo moko mi kemikol mi wodhu piny ma timo tic moko. Ku lapor, acetonitrile copo kadhu kud i nucleophilic substitution reactions ku cyano group pare mi wodhu amine nyo alcohol compounds.
I tic mi yath, acetonitrile jutiyu kudu lee i yubu yath man yub mi yiku yath. Ecopu jwigo kit yath matung tung man piny ma wok ikind yath, makonyo tic maber pa kemikol. Ku lapor, i yik pa yath moko ma jwigo two man yath mi adunde, acetonitrile copo timo tic calu piny ma jwigo piny ma nyayu rwom pa tic man adwogi. Mi medo, acetonitrile jucopo tiyo kudu pi ketho yath ubed maleng man maleng.
I tic mi wil man piny mi deyo, acetonitrile jutiyu kudu pi yiku man lwoko piny ma leng. Ecopu bedu ni tiyo kudu pi kwanyu piny ma leng, calu moo ma leng kud i yen. Mi medo, acetonitrile jucopo tiyo kudu pi yubu jamb nguce ma ku nguce ma ukoc pi jamb tedu man piny mi deyo.
I tic mi cuma, acetonitrile jutiyu kudu calu piny mi yweyu man mi lwoko piny. Ecopu kwanyu piny madong man ma reco kud iwi piny ma tiyo ku mac, ma weko piny ma tiyo ku mac bedo maleng man timo maber. Ku lapor, i yubu semiconductor, acetonitrile jucopo tiyo kudu pi yweyu wi wafers, kwanyu photoresist residues man piny mukende ma reco.
Kadi bende tic kude utiye madwong, acetonitrile utiye piny ma nyai man ma rac, man tic kude man gwoko pare mitu gwok ma tek. Acetonitrile nyai yot yot i yamu, ci umitu jutii kudu kama yamu wok iye maber. Mi medo, yath pa acetonitrile utiye ku tho moko, man jam gwoko kum maber umitu juketh ikare ma jutiyo kudu pi gwoko adila man wang. I tic mi yubu piny, tic ku acetonitrile pol kare timere i kabedo ma cego pi jwigu peko mi kabedu.

I ayi ma kicoko, acetonitrile, calu piny ma pire tek ma jutiyo kudu pi yubu piny ma kwo man piny ma nyayu pii, timo tic ma pire tek i tic matung tung. E medo kero man adwogi pa tic pa kemikol kende ngo ento ekonyo bende dongo pa tic mi kare eni. Ku dongo dongo mi ryeko, yore mi tic ku acetonitrile bibedo malac.
