1.Using NaF as carrier,a carrier distillation method of emission spectrographic and DC excitation for the determination of 21 impurity elements,i. e. Fe,Si,Ti,V,Cr,Ca,Mn,Mg,Al,Ni,Cu,Bi,Sn,Pb,Yb,Y,Cd,Nb,Mo,Sb,La in powder of tungsten-cobalt alloy by WSP-1 model plane-grating spectrograph was described.
3.Nerolidol and methyl acetoacetate underwent Carroll reaction and the reaction mixture was fractionatedto give a fraction rich in (5E,9E)-farnesylacetone followed by Grignard reaction and Carroll reaction to give teprenone withan overall yield of 19.1% and purity of 98%.
4.It is not always easy to separate a mixture of liquids into pure substances by fractional distillation.
5.Bubble?point vapor pressures along with the coefficients of Antoine equation correlation were reported for 22 hydrocarbon fuel fractions with different true boiling temperature ranges to investigate the relationship of vapor?liquid phase equilibrium constants between wide and narrow fuel fractions? The fuel samples were originated from crude oils with the initial atmospheric boiling temperature from 348?15? K to 623?15?
6.STUDY ON PRODUCTION OF 25~# TRANSFORMER OIL FROM DISTILL-ATE OIL WITH HIGH ACID VALUE BY FURFURAL REFINING PROCESS
8.Research on safety assessment of craftwork of distilled C2 adding hydrogen based on Dow
9.In this thesis the water content in C4 distillation is determined with Carl-Fisher-Coulomb potentiometric method.
10.Methods by calculating the structural parameters and functional group concentration ware applied to do the assessment of the average chemical structure of the fractions (>350℃)of Fushun shale oil (FSO) and Maoming shale oil(MMO).
