The reactions are selectively compatible with such diverse slurry additives as alcohols, glycols, glycerol, urea, formamide.
与醇类, 二醇类, 丙三醇, 尿素, 甲酰胺各种浆液附加物进行反应时,在相言性方面是有选择性的.
Polyurethane elastomers based on glycols ( PEA, PPG PTMG ) , diisocyanate ( TDI ) and chain extender ( E - 300 ) were prepared.
以多元醇 ( PEA, PPG,PTMG ),PDI, E300为原料,制备了 PU 弹性体.
A new process of Hydration of propylene oxide to glycols was introduced.
采用反应精馏新工艺由环氧丙烷水合制丙二醇.
Both steps use fluids that contain glycols, chemicals that have a lower freezing point than water.

But the key is those glycols, which reduce freezing points to as low as 60 degrees below zero Fahrenheit.

The thicker fluid stays on the plane longer and lets the glycols keep things from refreezing while the plane is waiting.
