| titleOfInvention | A kind of preparation method of terephthalic acid polyester polyether polyol |
| abstract | The invention discloses a kind of preparation method of terephthalic acid polyester polyether polyol, comprise the following steps: 1) will reclaim in alcohol, terephthalic acid, organotin disposable input pet reaction still; Pass into N2, slowly heat up, insulation; Vacuumize, treat product acid number≤1.5mg? stopped reaction during KOH/g; Cooling press leaches material, obtains terephthalic acid kind polyester polyvalent alcohol.2) above-mentioned intermediate product and multi-metal cyanide, the vitriol oil are dropped in polyether reactant still, decompression; Drop into the mixture of propylene oxide, oxyethane to reactor, slowly heat up, reaction 0.5 ~ 1h, continue to heat up, and be incubated 0.5 ~ 3h; Treat that Pressure Drop is to below-0.04MPa, vacuumizes, pressure and temperature maintain respectively-0.095 ~-0.090MPa, 105 ~ 110 DEG C; Cooling press leaches material, obtains terephthalic acid polyester polyether polyol. |
