    • The present invention provides a method of preparing sodium formyl acetone using acetone, methyl formate and sodium methoxide as raw materials. A mixture consisting of an acetone and a methyl formate is supplied to a methanol solution of sodium methoxide, or an acetone and a methyl formate are separately supplied simultaneously to the methanol solution of sodium methoxide. The resultant mixture is sufficiently stirred over a predetermined period of time so as to carry out the reaction to form sodium formyl acetone. Also provided is a method of preparing 4,4-dimethoxy-2-butanone. In this method, the reaction mixture obtained in the reaction to form sodium formyl acetone is directly charged into a reaction vessel simultaneously with sulfuric acid to neutralize and acetalize sodium formyl acetone contained in the reaction mixture so as to obtain 4,4-dimethoxy-2-butanone.
    • 本发明提供使用丙酮,甲酸甲酯和甲醇钠作为原料制备甲酰基丙酮钠的方法。 将由丙酮和甲酸甲酯组成的混合物供应到甲醇钠的甲醇溶液中,或者丙酮和甲酸甲酯分别同时供应到甲醇钠的甲醇溶液中。 将所得混合物在预定的时间内充分搅拌,以进行反应以形成甲酰基丙酮钠。 还提供了制备4,4-二甲氧基-2-丁酮的方法。 在该方法中,将形成甲酰基丙酮的反应中得到的反应混合物与硫酸同时直接加入到反应容器中,中和反应混合物中所含的甲酰基丙酮缩醛,得到4,4-二甲氧基-2 丁酮。

    • A method and an apparatus in which an engine is controlled by a microcomputer on the basis of a basic ignition advanced angle, an ignition advanced angle unit-correction value and a supplied air quantity unit-correction value stored in maps for providing a best fuel consumption corresponding to each of various running conditions such as an intake air quantity, engine revolution number, and the like, as well as on the basis of correction factors corresponding to running conditions such as stable running and unstable running. In order to obtain a best fuel consumption in a stable running state, the ignition advanced angle and the supplied air quantity are parallelly corrected by the ignition advanced angle unit-correction value and the supplied air quantity unit-correction value respectively while discriminating increment of torque so that this correction is successively repeated until a best fuel consumption is reached. The ignition advanced angle correction factors and the air quantity correction factors are stored, updating the previously stored data, on the basis of the respective total correction values searched by the successively repeated corrections.
    • 基于点火提前角,点火提前角单位校正值和存储在地图中的供给空气量单位校正值,由微型计算机控制发动机的方法和装置,以提供最佳燃料消耗 对应于诸如进气量,发动机转数等的各种运行条件中的每一个,并且基于对应于运行条件如稳定运行和不稳定运行的校正因子。 为了在稳定的运行状态下获得最佳的燃料消耗,点火提前角和供给的空气量分别通过点火提前角单位校正值和供给的空气量单位校正值并行校正,同时识别扭矩增量 使得该校正被连续地重复,直到达到最佳燃料消耗。 基于由连续重复校正搜索的各个总校正值,存储点火提前角修正系数和空气量校正因子,更新先前存储的数据。
