    • A process for preparing a lactate which includes: (a) preparing lactonitrile from prussic acid and acetaldehyde, (b) hydrating the lactonitrile to form lactamide, (c) forming the desired lactate and formamide from lactamide and formate (or methanol and carbon monoxide), (d) separating and collecting components, having a lower boiling point than that of lactate from the reaction liquid in step (c), by distillation under specified conditions, and (e) dehydrating formamide from step (d) to form prussic acid and recycling the prussic acid to step (a). Heretofore, lactates had been manufactured by forming lactonitrile (cyanohydrin) from acetaldehyde and prussic acid, and then esterifying lactonitrile with a mineral acid or the like. However, in this conventional process, ammonium salts were formed as by-products in an amount equal to that of the lactate. According to the present invention, a lactate can be efficiently manufactured on a commercial scale without forming a large amount of the ammonium salts as by-products. In particular, the yield of the lactate can be increased by controlling the formation of 2-formyloxy propionate and also a dimer of a lactate.
    • 一种制备乳酸的方法,其包括:(a)从丙二酸和乙醛制备乳腈,(b)使乳腈水合形成乳酰胺,(c)从乳酰胺和甲酸盐(或甲醇和一氧化碳)形成所需的乳酸盐和甲酰胺, ,(d)在步骤(c)中通过蒸馏从特定条件下蒸馏分离和收集沸点低于乳酸盐的组分,并且(e)从步骤(d)中将甲酰胺脱水形成二甲苯, 将重要的酸回收到步骤(a)。 迄今为止,已经通过从乙醛和氢溴酸形成乳腈(氰醇),然后用无机酸等使乳腈酯化来制造乳酸盐。 然而,在该常规方法中,形成铵盐,其量等于乳酸盐的副产物。 根据本发明,可以以商业规模有效地制造乳酸盐,而不会形成大量的作为副产物的铵盐。 特别地,通过控制2-甲酰氧基丙酸酯和乳酸二聚体的形成可以提高乳酸产率。

    • A vehicle-mounted air purifier 1 includes a main unit incorporating an ion generator. The main unit is removably arranged within a passenger space inside a vehicle. For example, if a beverage container holder 90 is provided inside the vehicle, the main unit can be removably arranged within the passenger space when given a cylindrical shape that permits it to be held in the beverage container 90. The power from which the vehicle-mounted air purifier 1 operates can be taken from a cigarette lighter power outlet 91 provided inside the vehicle through a connection cable 92. The main unit is thus arranged directly within the passenger space, and the ions generated by the ion generator inside are fed into the passenger space with higher efficiency. The main unit is removably arranged as an independent unit. Thus, even when the ion generator breaks down or otherwise its replacement becomes necessary, the arranged ion generator can be removed readily and replaced easily.
    • 车载空气净化器1包括结合有离子发生器的主单元。 主机可拆卸地布置在车辆内的乘客空间内。 例如,如果饮料容器保持器90设置在车辆内部,则当给定允许其保持在饮料容器90中的圆筒形状时,主单元可拆卸地布置在乘客空间内。 安装空气净化器1的操作可以通过连接电缆92从设置在车辆内部的点烟器电源插座91取走。因此,主单元直接布置在乘客空间内,并且由离子发生器内部产生的离子被馈送到 乘客空间效率更高。 主单元可拆卸地布置为独立单元。 因此,即使当离子发生器发生故障或者其它替换变得必要时,排出的离子发生器也可以容易地被去除并容易地更换。
