1. The relationships between activated carbon characteristics and CO2 gasification time were investigated at the KOH/char ratios of 1 and 4 for studying the effect of the combined activation process. At the low KOH/char ratio, long CO2 gasification time significantly increased the specific surface area and mesopores volume ratio. At KOH/char equal to 4 and CO2 gasification time equal to 30 minutes, the highest surface area of 2844 m2/g was obtained.
2. The activation of three alkoxylation reagents including NaOMe, sodium and KOH was investigated which indicated that NaOMe was the best alkoxylation reagent.
3. The effect of mildewed soybean on soybean meal was studied by evaluation of oil content, crude protein content, protein solubility in KOH solution, urase activity, color and flavor.
4. Koh Samui, a place where you can have a wonderful holiday.
5. The beauty of that moment on Koh Samui provided me with such inspiration.
6. Denise: Actually, a lot of our clients are planning to go to Koh Samui which is something we are promoting right now and it's been quite successful.
7. Dimercaptoethyl sulfide, 2-phenylthioethane thiol and 2-mercaptomethyl-1, 4-dithiahexane were synthesized through thioureamethods, then the thiol methacrylate esters (MESDMA, MEPSMA andMMDMA, respectively) were prepared with reversed PTC method (droppedKOH solution.) in the first time. The source and purifying methods of theforeign substance bearing 〓 group in MES were discussed.
8. In order to raise the conversion rate and purity of biodiesel, the technology for production of biodiesel by using rapeseed oil was studied through the transesterification reaction of fatty acid and methanol with catalyst of KOH. The technological parameters including the amount of methanol, the amount of catalyst, temperature and reaction time were investigated.
9. It can be concluded that KOH can be served as dehydrating reagent in replacement of DBU.
10. AC is prepared from a commercial PC from CNPC Liaohe Petrochemical Company as the precursor and KOH for activation, the effect of different preparation conditions on the properties of AC was investigated by using orthogonal design and single factor analysis.
11. Adsorption process could be divided into three to four stages with relative pressure of ca. 10〓～10〓, 10〓～10〓, 10〓～10〓, and 0.9～1. These were attributed to different pore filling with pore size changing. Activated diffusion was discussed in detail and in evidence by theory calculation. The micropore volume and the external surface area were assessed by the high-resolution α〓 plot method. It was shown that the adsorption filling process for samples activated by different methods with the increasing of activation degree was quite different. For steam-activated series of samples, the pore filling with the increasing of activation degree changed from micropore filling to mesopore filling until macropore filling at relative pressure closing to unity. For air-activated series samples, all samples showed mainly ultramicropore filling. For KOH-activated series samples, the samples showed mainly ultramicropore and supermicropore filling, and supermicropore filling was dominant.
12. Koh Larn is the largest of Pattaya's archipelago.
13. Tangent also interviewed three elders: Mr Han Tan Juan, Mr Yeng Pway Ngon, and Professor Koh Tai Ann.
14. Therefore, an AC with a surface area as high as 2336 m~2g~(-1) was prepared from the coke oxidized by 15%H_2O_2 solution with a 3:1 KOH/Coke ratio.
15. The corrosion inhibiting ability of sodium dodecyl benzene sulfonate and hexamethylenetetramine as additives are also studied.
16. Therefore, how to optimize the technical conditions and lower KOH/coke ratio is of great value for further research.
17. The thermoreversibility of phenol formaldehyde resin - borate hydrogels as a function of polymer concentration, sodium tatroborate concentration and KOH concentration was investigated by the gel - melting temperature s.
18. Other medicine show various sensitivity and tolerance.

19. Treatment of phenylthiophosphonic dichloride with toluene by Friedel-Crafts reaction afforded bis(4-methylphenyl) phenylphosphine sulfide, which was oxidated into key intermediate, bis(4-carboxyphenyl) phenylphosphine oxide in the presence of KMnO4 in aqueous solution of pyridine and potassium hydroxide in two step, respectively.
20. Synthesis of dipropyl carbonatefrom dimethyl carbonateand propyl alcohol by transesterification was studied.
