Ethylene Glycol Monoethyl Eteri Acetate With 111-15-9
Inowanikwa nekuita kwe ethylene glycol monoethyl ether uye acetic anhydride. Sanganisa acetic anhydride uye concentrated sulfuric acid. Mushure mekupisa kusvika ku130 ° C, zvishoma nezvishoma wedzera ethylene glycol monoethyl ether dropwise. Tembiricha yekupindura inochengetwa pa130-135 ° C. Kuyerera kwakawedzerwa kwe1-2 h, uye tembiricha yereflux yaive 140 ° C. Mushure mekutonhodza, gadzirisa ne sodium carbonate kusvika pH=7-8, wobva waoma neindasitiri anhydrous potassium carbonate. Iyo desiccant yakasefa kuti iparadzwe, uye iyo distillate pakati pe150-160 ° C yakaunganidzwa. Kuparadzaniswa kunoitwa zvakare, uye chikamu pa155.5-156.5 ° C chinounganidzwa sechigadzirwa chakapedzwa. Inogonawo kuwanikwa ne catalyzing ethylene glycol monoethyl ether uye acetic acid ine concentrated sulfuric acid uye refluxing mu benzene.
