（産業上の第１］用分野）
本発明は、モノクロル酢酸の様なりロル化低級脂肪酸と
無水炭酸ソーダを用いてクロル化低級脂肪酸ソーダを製
造する方法に関する。DETAILED DESCRIPTION OF THE INVENTION (First Industrial Field) The present invention relates to a method for producing chlorinated lower fatty acid soda using a chlorinated lower fatty acid such as monochloroacetic acid and anhydrous soda carbonate.
（従来技術）
クロル化低級脂肪酸、例えば、七ノクロル酢酸ソーダは
、一般に結晶状またはフレーク状の固体モノクロル酢酸
と粉末状の固体無水炭酸ソーダを、攪拌混合型の反応機
に入れて製造できることが知られている。(Prior Art) It is known that chlorinated lower fatty acids, such as sodium heptanochloroacetate, can generally be produced by placing crystalline or flaky solid monochloroacetic acid and powdered solid anhydrous sodium carbonate in a stirring-mixing reactor. It is being
この場合、下式に示すように反応生成水が約８％発生す
る。In this case, about 8% of reaction product water is generated as shown in the formula below.
２ＣｔＣＨ２Ｃ００Ｈ＋Ｎａ２Ｃｏ３→２ＣｔＣＨ２Ｃ
ＯＯＮａ 十ＣＯ□＋Ｈ２０
このため含水量の少いモノクロル酢酸ソーダを得るため
には加熱乾燥が必要であるが、そのために温度を高くす
ると生成したモノクロル酢酸ソーダの加水分解が進みグ
リコール酸と食塩が生成し逆にモノクロル酢酸ソーダの
純度が低下する。2CtCH2C00H+Na2Co3→2CtCH2C
OONa 10CO□+H20 For this reason, heat drying is necessary to obtain sodium monochloroacetate with a low water content, but when the temperature is raised for this purpose, the hydrolysis of the produced sodium monochloroacetate progresses to produce glycolic acid and salt. Conversely, the purity of monochlorosodium acetate decreases.
従ってなるべく低い温度で反応及び乾燥を行なう必要が
あるが、この場合には反応速度及び乾燥時間が遅くなる
ため製造時間が長くなり、結局、食塩の生成量も多くな
ってしまう。この様な問題点を解決するための詳細な後
文ばこれまでのところ殆んど見られない。Therefore, it is necessary to carry out the reaction and drying at as low a temperature as possible, but in this case, the reaction rate and drying time are slowed down, resulting in a longer production time and, ultimately, an increase in the amount of salt produced. So far, there has been little detailed support for solving these problems.

ソーダの製造方法である。(Means for Solving the Problems) In order to achieve the above object, the inventors of the present invention have conducted various studies on manufacturing conditions and raw materials, and have found that a specific raw material is used and reaction drying is performed at a specific temperature. The inventors have discovered that high-quality sodium monochloroacetate can be produced in a short period of time and have arrived at the present invention. That is, in the present invention, when mixing chlorinated lower fatty acids and anhydrous sodium carbonate to produce chlorinated lower fatty acid soda, the reaction temperature is 45 to 65°C, and 10
This is a method for producing chlorinated lower fatty acid soda, characterized by using anhydrous soda carbonate containing 70% or more of particles of 0 to 200 mesh.
本発明に使用するクロル化低級脂肪酸とは例えばモノク
ロル酢酸、ジクロル酢酸、トリクロル酢酸、モノクロル
プロピオン酸、ジクロルプロピオン酸等がある。Examples of the chlorinated lower fatty acids used in the present invention include monochloroacetic acid, dichloroacetic acid, trichloroacetic acid, monochloropropionic acid, and dichloropropionic acid.
本発明に使用する無水炭酸ソーダは粒子径１００〜２０

の効果が十分に達成されない。The anhydrous soda carbonate used in the present invention has a particle size of 100 to 20
0 meshes, preferably 100-150 meshes 7
It is a powder containing 0% or more. Note that if it is less than 70 (X), the effects of the present invention will not be fully achieved.
無水炭酸ソーダの粒子径は、２００メソシユより細かい
と排気ダクトへの飛散が激しくなるため好ましくない。If the particle size of the anhydrous soda carbonate is smaller than 200 mesos, it is not preferable because it will scatter into the exhaust duct.
又、粒子径が１００メツシュより太きいものが多いと、
反応が遅くなり、反応が完結するまで水分の生成が続き
、結果的に乾燥時間が長くなるので好しくない。Also, if there are many particles with a diameter larger than 100 mesh,
This is undesirable because the reaction slows down and moisture continues to be produced until the reaction is completed, resulting in a longer drying time.
反応及び乾燥温度は、４５〜６５℃好ましくは５０〜５
５℃であるが、７０ ’Ｃを越えると食塩の生成が顕著
に早くなり、また４５℃を下根ると反応速度及び乾燥が
遅くなるため製造時間が長くなり、結局食塩の生成も多
くなるので好しくない。The reaction and drying temperature is 45-65°C, preferably 50-55°C.
The temperature is 5°C, but if it exceeds 70'C, the production of salt will be significantly faster, and if the temperature is lower than 45°C, the reaction rate and drying will slow down, resulting in a longer production time, and eventually more salt will be produced. So I don't like it.

よい。In carrying out the present invention industrially, chlorinated lower fatty acids such as monochloroacetic acid and the above-mentioned anhydrous soda are placed in a stirring-mixing reactor at a predetermined temperature, for example, at a temperature of 20 to 25 kg.
They may be charged in units of li+ at a charging ratio of about equimolar amounts to each other.
