    • The present invention relates to a method for producing alkyl lactate directly from ammonium lactate generated in a fermentation process. In detail, the present invention relates to a method for producing alkyl lactate directly from ammonium lactate, comprising a first step of producing a mixture comprising an aqueous solution of ammonium lactate generated in a fermentation process and trialkyl phosphate-based organic solvent extractants, and heating the mixture to prepare lactic acid; and a second step of performing an esterification reaction between the lactic acid prepared in the first step and alcohol to prepare alkyl lactate. According to the method of the present invention, a pretreatment process such as the addition of sulfuric acid required for preparing lactic acid is eliminated, and an esterification reaction between lactic acid and alcohol is performed simultaneously with the preparation of lactic acid in order to produce alkyl lactate, thereby producing alkyl lactate in an easier manner than conventional processes for producing alkyl lactate from lactate salts generated in a fermentation process, and, during an esterification reaction with lactic acid, effectively separating, from lactic acid or alkyl lactate contained in an organic solvent, water to be derived as a by-product, such that the reaction speed and yield rate can be improved and high-efficiency and high-purity alkyl lactate can be produced.
    • 本发明涉及在发酵过程中直接由乳酸铵生产乳酸烷基酯的方法。 详细地说,本发明涉及直接由乳酸铵生产乳酸烷基酯的方法,该方法包括:制备包含发酵过程产生的乳酸铵水溶液和磷酸三烷基酯类有机溶剂萃取剂的混合物的第一步骤,以及加热 混合物制备乳酸; 以及在第一步中制备的乳酸和醇之间进行酯化反应以制备乳酸烷基酯的第二步骤。 根据本发明的方法,除去了制备乳酸所需的添加硫酸等的预处理方法,同时在制备乳酸的同时进行乳酸和醇之间的酯化反应,以制备出烷基 乳酸盐,从而比在发酵过程中产生的乳酸盐生产烷基酯的常规方法更容易地制备乳酸盐,并且在与乳酸的酯化反应期间,有效地从包含在有机溶剂中的乳酸或乳酸烷基酯中分离出来 作为副产物得到的水,从而可以提高反应速度和产率,并且可以生产高效率和高纯度的乳酸烷基酯。

    • The present invention relates to a surface treatment method, and more particularly, to a method for coating the surface of a substrate with nanoporous material for heat transfer control. The method includes the steps of: producing a nanoporous material; depositing an organic functional group on the surface of a substrate where said nanoporous material is to be coated; and covalently bonding the nanoporous material to the surface of the subtrate. The method according to the present invention has the following advantages: the coating layer is provided with numerous active nucleation sites; enables gas to be stored in the pores; provides a large contact area between liquid and gas, high capillary pressure and excellent wettability; and enables a superior combination of bubbles and high bubble detachment frequency. Accordingly, the coating layer of the present invention provides a low temperature boiling point, a high critical heat flux and a high heat transfer coefficient. The present coating layer can be produced into a thin film having a thickness of a few microns or less, and can thus be used for cooling a substrate which generates a large amount of heat in a confined area, such as a computer CPU, LEDs, mobile phone, or the like. The present coating layer also overcomes the problem of increased heat resistance. The nanoporous material has a large surface area, and the coating layer is excellent in moisture absorbance and water repellence. The coating layer of the present invention is strongly bonded to the surface of the substrate, and can be used stably over extended periods without the coating layer peeling off even with extended exposure to vibrations.
