| Research Abstract |
In this research, our purposes are to develop the new reduction system from lingo-cresoles to lingo-alkanes and to apply its lingo-alkanes use for new fields. In the result of optimization about catalyst usage, alcohols as proton sources, and calcium as a reductant, we found that the reduction of lingo-cresoles (1g) with 0.1g of Rh/C (Rh: 5 wt%) and 10 mmol of metallic calcium in 5 mL of ethanol solution in a sealed tube gave the corresponding aliphatic compounds (=lingo-alkanes, it’s liquid) in quantitative yields, with IR and 1H NMR. In the next step, the obtained liquid was put into the mixture of two polymers, that are polyethylene (Mw = 35,000) and polypropylene (Mw = 14,000) at 200 ℃, then was kept to stir for 30 min. The surface of mixed polymers was observed under SEM-EDS and IR after cooling. In SEM-EDS, we found that the composition is a constant in any surface of mixed polymers. Moreover, IR also shows the homogeneous functional structure of mixed polymers compare to the surface conditions and the structure for mixture of two virgin polymers without lingo-alkanes.
