According to the change of the kinds of elements content in slag, F in slag volatilizes in the form of KF and NaF, KF volatilizes much more easily than NaF, KF plays a leading role in the F volatilization, theoretical analysis shows that the saturation vapour pressure of KF in the test slag is 31. 4 times of NaF; when F content is far more than K, KF volatilization is first order grade reaction, it is dominated by K content, the apparent activate energy is 275. 30KJ/mol.

Little literature on the aspect of surfactants containing boron with long-carbon chain alkyls had been found.Using diethanolamine, boric acid, hexadecanol as starting materials, after a series of reaction such as vapour phase process bromizating, esterifying, alkylating, a new type of surfactants with boron RNB had been obtained. The structures of the compounds had been identified by elemental analysis, IR and HNMR.
