Fortunately, the moisture resistance property of superabsorbent polymer was obviously enhanced when the resin was treated by epoxy chloropropane and diethylene glycol.

Effect of Epoxy Chloropropane Dosages on the Moisture Resistance of SAP.
Distilled water at different mass ratios ([H.sub.2]O/[C.sub.2][H.sub.5]OH = 20%, 40%, 60%, 80%) was added in the mixture of 15% epoxy chloropropane and absolute ethanol, and the moisture resistance was tested.

In the experiment of synthesizing lignin-based epoxy resins, we blended bisphenol A with epoxy chloropropane in a 250 mL three-neck round-bottom flask equipped with a thermometer and mechanical stirrer, and the mixture was heated until bisphenol A dissolved completely into solution at 50[degrees]C.
OL, DLF, and DFL reacted with epoxy chloropropane to form epoxy resins were called OL-E, DLF-E, and DFL-E, respectively.
The 1 chloropropane
spectrum is often used as a textbook example because the carbons are numbered 1-3 from left to right as shown in Figure 2, and their associated NMR signals are also in the same order from left to right as shown in Figure 1.
Yet only four workplace health hazards -- lead, ionizing radiation, ethylene oxide, and dibromo chloropropane
(DBCP) -- are regulated in the United States partly because of their effects on human reproduction.
It was demonstrated that molecular oxygen in the test environment does not exert any influence on the adsorptive capacities of activated carbon for chloroform, chlorobenzene, or chloropropane
when the isotherms are conducted in deionized water.
