Igiciro cyiza cy'umusaruro Butylal (Dibutoxymethane) CAS: 2568-90-3
Amagambo asa
Formaldehyde dibutyl acetal ni asetali ikoreshwa mu gukora resins za sintetike, antiseptics, deodorants, na fungicides. Ikoreshwa kandi nk'inyongeramusaruro mu kongera umubare wa octane wa lisansi cyangwa umubare wa n-cetane wa mazutu no kugabanya umwotsi n'imyanda ihumanya.
Imikoreshereze ya Butylal
- Formaldehyde dibutyl acetal ni solvent idafite halogen kandi idahumanya cyane ishobora gukoreshwa mu gushonga ingero za polyethylene yo mu rwego rwo hasi (LDPE) mu gusesengura ikwirakwizwa ry'uburemere bwa molekile hakoreshejwe gel permeation chromatography (GPC). Ishobora kandi gukoreshwa nk'ikintu gitera ingaruka mu gutegura butoxymethyltriphenylphosphonium iyode, ikoreshwa mu guhuza karuboni ndetse no nk'ikintu cy'ingenzi mu guhuza organic synthesis.
- Uburyo bwo gutegura: Icupa ririmo garama 15 (0.5 mole) ya paraformaldehyde, garama 74 (1.0 mole) ya alcohol ya η-butyl, na garama 2.0 za ferric chloride idafite amazi bisubirwamo mu gihe cy'amasaha 10. Urupapuro rwo hasi rwa mililitiro 3-4 z'ibikoresho rurajugunywa hanyuma hongerwamo mililitiro 50 z'umuti wa sodium carbonate wa 10% w'amazi kugira ngo ferric chloride ikureho ferric hydroxide. Umuti unyeganyezwa uvanze na mililitiro 40 za hydrogen peroxide ya 20% na mililitiro 5 za 10% by'umuti wa sodium carbonate kuri 45°C kugira ngo haveho aldehyde isigaye. Umuti kandi wozwa n'amazi, wumuke, hanyuma uvangwe mu byuma bya sodium kugira ngo ubone garama 62 (78%).
