  • The absorption rate of carbon dioxide with 2-amino-2-methyl-1-propanol(AMP) was measured in such non-aqueous solvents as methanol, ethanol, n-propanol, n-butanol, ethylene glycol, propylene glycol, and propylene carbonate, and in water at 298 K and 101.3 kPa using a semi-batch stirred tank with a plane gas-liquid interface. The overall reaction rate constant, obtained under the condition of fast reaction regime, from the measured rate of absorption was used to get the elementary reaction rate constants in complicated reactions represented by reaction mechanism of carbamate formation and the order of overall reaction of $CO_2$ with amine. The correlation between the elementary reaction rate constant and the solubility parameter of the solvent was also presented.

  • The reaction rate of $CO_2$ with 2-amino-2-methyl-1-propanol (AMP), MEA monoethanolamine(MEA) and diethanolamine (DEA) in aqueous solutions has been determined using a stirred vessel with a plane gas-liquid interface over a wide range of concentrations of amines at different temperatures. The results show that the overall reaction rate is first order with respect to both $CO_2$ and amine. The reaction rate constant varies with temperature according to the relationship which agrees with the experimental data. The proposed interpretation is that the kinetic rate determining step is a reaction of $CO_2$ with amine to form carbamic acid which is then totally and immediately ionized.

  • Carbon dioxide was absorbed into the aqueous nanometer sized colloidal silica solution of 0-31 wt% and 2-amino-2-methyl-1-propanol of $0-2kmol/m^3$ in a flat-stirred vessel with the impeller of various sizes and speeds at $25^{\circ}C$ and 0.101 MPa to measure the absorption rate of $CO_2$. The volumetric liquid-side mass transfer coefficient$(k_La)\;of\;CO_2$ was used to obtain the empirical correlation formula containing the rheological behavior of the aqueous colloidal silica solution. Reduction of the measured $k_La$ was explained by the viscoelastic properties of the aqueous colloidal silica solution. The theoretical value of the absorption rate of $CO_2$ was estimated from the model based on the film theory accompanied by chemical reaction and compared with the measured value.

  • Black fermented garlic includes many pharmacological components. Therefore, in this study, black fermented garlic wine was manufactured and its flavor compounds were investigated difference of aging chips from America and France. The fermented wine was stored at $10^{\circ}C$ for 6 months. GC/MS was used for the flavor components analysis. Wine using American chip contained 2-methyl-1-propanol, 3-methyl-1-butanol, 2-methyl-1-butanol, acetaldehyde, butanoic acid, octanoic acid, 1,1-diethoxyethane, and allyl methyl sulfide. 1-Propanol, 2-methyl-1-propanol, 3-methyl-1-butanol, acetaldehyde, acetic acid, propanoic acid, butanoic acid, octanoic acid, 2-heptanone, 1,1-diethoxyethane, N-amino32-hydroxypropanamidate, n-butylamine, and chloroacetonitrile were detected as major flavor compounds using France chips. Especially, the wine contained allyl methyl sulfide that was resulted from black fermented garlic. There were more compounds that smell like fruit in the wine using American chips relatively. And allyl methyl sulfide was detected only in the wine using America chips. Whereas acetic acid was detected only in the wine using France chips.

  • Absorption rate of carbon dioxide was measured in the aqueous xanthan gum (XG) solution in the range of 0-0.15 wt% containing 2-amino-2-methyl-1-propanol (AMP) of $0-2\;kmol/m^3$ in a flat-stirred vessel with an impeller of 0.05m and agitation speed of 50rpm at $25^{\circ}C$ and 0.101 MPa. The volumetric liquid-side mass transfer coefficient ($k_La$) of $CO_2$, which was correlated with the viscosity and the elastic behavior of XG solution containing Deborah number as an empirical formula, was used to estimate the chemical absorption rate of $CO_2\;(R_A)$. $R_A$, which was estimated by mass transfer mechanism based on the film theory using the physicochemical properties and the kinetics of reaction between $CO_2$ and AMP, was compared with the measured rate. The aqueous XG solution with elastic property of non-Newtonian liquid made $R_A$ increased compared with Newtonian liquid based on the same viscosity of the solution.

  • In this study, densities of water + N-Methyldiethanolamine (MDEA), Water + 2-Amino-2-Methyl-1-Propanol (AMP), MDEA + AMP binary systems and Water+MDEA+AMP ternary system were measured over the full range of composition at temperatures from 303.15 K to 333.15 K by using an Anton Paar digital vibrating tube densimeter (DMA4500). The experimental excess volumes have been obtained from the experimental density results and have been fitted using the Redlich-Kister-Muggianu expression. The parameters obtained from the binary excess volume data were used for the correlation of ternary system with one additional ternary parameter for each isotherm. All investigated binary and ternary systems are completely miscible, because the values of excess volume are negative under the examined conditions.

  • CMP (Chemical Mechanical Polishing) processes have become essential for creating multilayered component structures in semiconductor manufacturing. Typically, the slurry composition in CMP processes involves a balance of three components such as ceria, dispersant, and deionized water. In this study, we conducted research on the stability of ceria slurries using an amphoteric surfactant with controlled concentrations of AMP (2-Amino-2-methyl-1-propanol). The results indicated pH stabilization influenced by carboxylic (-COOH) groups depending on the AMP concentration. Additionally, there was no occurrence of aggregation in the ceria slurry, confirming the absence of dispersion stability issues.
