Colloidal dispersions of tungstic acid (H(2)WO(4)) have been prepared in water/(TX-100+alkanol)/n-heptane water-in-oil microemulsion media by reacting Na(2)WO(4) with HCl. The effects of alkanol chain length, TX-100/alkanol mass ratio, temperature, and dilution at different [water]/[TX-100] mole ratios (omega) have been studied by the dynamic light scattering technique. The formation of H(2)WO(4) in the microwater pool has been established by FT-IR measurements. The particle sizes and shapes in microemulsion media and in isolated states have been measured by TEM and SEM techniques. The enthalpy of formation of H(2)WO(4) in the water pool of the microemulsions has also been determined microcalorimetrically. Copyright 2001 Academic Press.
通过使钨酸钠（Na₂WO₄）与盐酸反应，在水/（TX - 100 + 链烷醇）/正庚烷油包水微乳液介质中制备了钨酸（H₂WO₄）的胶体分散体。采用动态光散射技术研究了链烷醇链长、TX - 100/链烷醇质量比、温度以及在不同水/ TX - 100摩尔比（ω）下稀释的影响。通过傅里叶变换红外光谱（FT - IR）测量确定了微水池中H₂WO₄的形成。利用透射电子显微镜（TEM）和扫描电子显微镜（SEM）技术测量了微乳液介质中和分离状态下的颗粒大小及形状。还通过微量量热法测定了微乳液水池中H₂WO₄的生成焓。版权所有2001年学术出版社。
