Falling film reactor product color and other quality parameters of the forecast

s accumulation. Film with the previous forecast of embarrassing type of free SO different in the accumulation near the interface of free SO predictable and proof of the reduction of organic reactants with increasing carrier gas flow rate is not the correct dilution of the gas phase SO, but the subsurface liquid interface updates faster. Predictive Control of mass transfer phase (gas or liquid) change the starting point in the reactor, gas SOa were higher, the higher conversion rate; and at the starting point after the low level of gas SOs, the model predicts a higher conversion rate in the reactor starting point is the interface temperature 』Du sharp peak, also predicted a low rate of gas SOs when the peak mole higher. This can reduce the conversion rate through the interface description. For the higher mole fraction, the reduction of the organic reactant. Conduction convection in liquid phase is not obvious. With \Mole fraction and SOa / molar ratio of organic matter and increase the color reduction. Even if the kinetic parameters are known, for the homogeneous compounds (such as long chain alcohols), these parameters can be considered almost constant. Thus, if the experiment has been done, and get the product color is determined, then the model can be defined for the subordinate solution as: cl-j a cdr under these conditions the color points residue cl. The new conditions for the study of color seeking Shuaixia type integral cT: Rb ¨ Tan Po Po crucible Ding 2,[link widoczny dla zalogowanych], 1994 Daily he learned: CI-forecast earnings Color Long Hui useful tool, the study of static long-chain alkyl CI methyl ether and for the control of the color he and sulfuric acid chemical properties of other compounds present a even more interesting is the ability to predict the phase of non-purpose good-product of reasoning,[link widoczny dla zalogowanych], their glistening variability and not on the content of kinetic Wu, For example, using a similar method can predict qualitatively have been identified. Alcohol in the decomposition products. Translated by Li Wei Zhuo Huanzhen in school, type set and lost to help pull out 7. Sail. A: duo Li, Qu Bo 』* pull out. Hard water can crop away from the words used in surfactant / 0 lead rich like Krafft in 1894 found that the water solubility of soap in a dramatic increase in temperature above, from the almost insoluble state (~ 0.02wt) increased 4 ℃ ~ 5c, Series degree of melting increases 3O ~ 60. Later, the rapid dissolution of the surfactant is called the Krafft point temperature. This important fact of the detergent, temperature is very important physical subsequently confirmed by many researchers. However, the dissolution mechanism of these phenomena is clarified after 78 years. Common use of the soap touched the Ca calcium salt that is generated,[link widoczny dla zalogowanych], the Krafft point l00 ℃ or more, even if the water does not dissolve in the series Wei, it is not used in hard water. 1Krafft points and relating to the teaching of physical meaning in order to better understand the physical properties of surfactant solution was studied on the Krafft point, get a new idea that the Krafft point is the melting point of surfactant hydration and the surface of the liquid state of water table Parties to fit active agent (micelles) seen by phase. The proposed two new ideas to break the sense, after 76 years to figure out the physical meaning of the Krafft point. Figure 1 shows the CzH: sso. Na solubility in water changes with temperature, surface active agent dissolved in the relationship between change and the Krafft point. Figure 1, the area below the surface active agent dispersed in water solution with a single series. Temperatures below the Krafft point,[link widoczny dla zalogowanych], adding more than soluble surfactant series, defined as the formation of hydrated-solid phase Ⅱ of surfactants, in addition. Temperatures above the Krafft point. Melting solid surface active agent to form a liquid state. At this time, not very strong for the second hydrophilic alcohols and glycerol ester, liquid form of the agent and the formation of monodisperse saturated solution of the I phase. However, hydrophilicity of the water (either a 0 boat temperature (℃) in the saturation solubility curve and Ktaff! The * Department of Figure 1CH2sSO | Na monodisperse in water temperature dependence of saturation concentration of a number) was dissolved in surfactant agent in the case, the hydrophobic surfactant and water is not close to form or enter into a limited number of association units (ie, micelle), so I formed micellar solution phase. Head H micelle hydrophilic surfactant in the melting point (Krafft point) above the temperature of the formation of I-phase micellar solution, the solubility increased dramatically. And the melting point of the same, Krafft point of equilibrium solution along with the changes in ion concentration gradually changes. For normal material, the solubility of monodisperse saturation B; and the surface active material to form a limited number of molecular association, the solution was transparent,[link widoczny dla zalogowanych], similar to the thermodynamic phase Ⅱ, saturated solubility curve is not a single dispersion curve of hydrated surfactant from a solid into a liquid state at the curve known as the dissolved N. 0 Total B | f = 0
