Adipate esters for industrial use ; determination of acidity to phenolphthalein ; volumetric method .
工业用己二酸酯;对酚酞的酸度测定;体积测定法。
The polyester , polythylene adipate , was removed from the reactor .
将聚酯,聚已酸乙稀酯从反应器中拿出来。
The application of the high-gravity ( higee ) system at preparing ammonium adipate , not only fast reaction but also more energy-efficient , has not allowed ammonia to escape , even is an achievement in environmental protection and economic benefits .
