Specifically, when performing the reaction of the production of sodium lauryloxybenzenesulfonate as a reaction solvent using a mixed solvent having a mixing ratio of 9:1 to 7:3 with water and acetone, it was confirmed that the yield increased when using only distilled water. , When the mixing ratio was 8:2, it was confirmed that the yield was the highest with 78%. On the other hand, when the ratio of distilled water and organic solvent is 6:4, the yield is 61%, and it is confirmed that the yield is reduced than when only distilled water is used.
소듐 노나노일옥시벤젠술포네이트의 제조반응에서 반응용매의 증류수와 유기용매의 혼합비율에 따른 수득율을 확인한 결과, 증류수와 유기용매의 혼합비율이 9:1 내지 7:3일 때 증류수만 이용할 때 보다 수득율이 증가하는 것을 확인하였으며, 혼합비율이 8:2일 때 77%로 수득율이 가장 높음을 확인하였다. 반면, 증류수와 유기용매의 비율이 6:4일 때 수득율이 52%로 나타나 증류수만 이용할 때보다 수득율이 감소하여 확인하였다. When checking the yield according to the mixing ratio of distilled water and organic solvent of the reaction solvent in the production reaction of sodium nonanoyloxybenzenesulfonate, when using only distilled water when the mixing ratio of distilled water and organic solvent is 9:1 to 7:3 It was confirmed that the yield was more increased, and when the mixing ratio was 8:2, it was confirmed that the yield was highest at 77%. On the other hand, when the ratio of distilled water and organic solvent is 6:4, the yield is 52%, which is confirmed by a decrease in yield than when only distilled water is used.
즉, 반응용매로 물 또는 유기용매(아세톤, 에틸아세테이트, 톨루엔, 아이소파-G 및 테트라하이트로퓨란(tetrahydrofuran, THF))를 단독으로 이용하여 반응을 수행한 결과, 아세톤, 에틸아세테이트, 톨루엔, 아이소파-G 또는 테트라하이트로퓨란(tetrahydrofuran, THF)을 단독으로 사용하여 반응을 진행할 때는 반응이 진행되지 않았으나, 물을 반응용매로 이용할 경우, 소듐 아실옥시벤젠술포네이트를 제조할 수 있음을 확인하였다.That is, as a reaction solvent, water or an organic solvent (acetone, ethyl acetate, toluene, isopa-G, and tetrahydrofuran (tetrahydrofuran, THF)) was used as a result of the reaction, acetone, ethyl acetate, toluene, The reaction did not proceed when the reaction was carried out using isopha-G or tetrahydrofuran (THF) alone, but it was confirmed that sodium acyloxybenzenesulfonate can be prepared when water is used as the reaction solvent.

After the dropping was completed, the reaction was performed for 1 hour while maintaining the temperature of the reactor at 28°C and the pH at 7 to 9. The catalyst used was tetra-n-butylammonium bromide (TBAB), a quaternary ammonium salt, based on the total weight of the reaction solvent, sodium hydroxybenzene sulfonate, aqueous sodium hydroxide solution and lauryl chloride. Sodium lauryloxybenzenesulfonate was prepared by adding 0.4% by weight. In addition, sodium lauronyloxybenzenesulfonate was prepared by performing the reaction in the same manner, except that lauryl chloride was changed to nonanoyl chloride.
따라서 본 발명의 반응시키는 단계는 반응기에 상기 반응용매를 첨가하는 단계, 소듐하이드록시벤젠술포네이트를 첨가하는 단계, 소듐하이드록사이드 수용액을 첨가하는 단계, 촉매를 첨가하고 교반하는 단계 및 상기 아실클로라이드를 첨가하여 반응을 진행하는 단계를 포함할 수 있다.Therefore, the step of reacting the present invention includes adding the reaction solvent to the reactor, adding sodium hydroxybenzenesulfonate, adding a sodium hydroxide aqueous solution, adding a catalyst and stirring, and the acyl chloride It may include the step of adding to proceed the reaction.

상기 반응시키는 단계에서 반응용매 800 내지 1200g 기준으로, 상기 소듐하이드록시벤젠술포네이트 0.5 내지 1.5몰(mol), 20 내지 80% 소듐하이드록사이드 수용액 50 내지 100g 및 상기 아실클로라이드 0.5 내지 1.5몰(mol)으로 첨가할 수 있다.In the reaction step, based on the reaction solvent 800 to 1200 g, the sodium hydroxybenzene sulfonate 0.5 to 1.5 mol (mol), 20 to 80% sodium hydroxide aqueous solution 50 to 100 g and the acyl chloride 0.5 to 1.5 mol (mol) ).
상기 촉매는 상기 반응시키는 단계에서 첨가된 상기 반응용매, 상기 소듐하이드록시벤젠술포네이트, 상기 소듐하이드록사이드 수용액 및 상기 아실클로라이드의 전체중량 기준으로 0.1 내지 1.5 중량%로 첨가할 수 있다. The catalyst may be added in an amount of 0.1 to 1.5% by weight based on the total weight of the reaction solvent, the sodium hydroxybenzene sulfonate, the aqueous sodium hydroxide solution and the acyl chloride added in the step of reacting.
촉매가 0.1 중량% 미만으로 첨가될 경우, 반응시 수득율이 떨어지고, 생성되는 부반응물이 많으며, 촉매가 1.5 중량% 초과로 첨가될 경우, 수득율이 크게 증가하지 않으며 효율이 떨어지는 단점이 있다.When the catalyst is added in an amount of less than 0.1% by weight, the yield decreases when reacting, and many side reaction products are produced. When the catalyst is added in an amount of more than 1.5% by weight, the yield does not significantly increase and efficiency is deteriorated.
본 발명의 일실시예에서 반응온도에 따른 소듐 라우릴옥시벤젠술포네이트 또는 소듐 노나노일옥시벤젠술포네이트의 수득율을 비교하고자, 증류수를 반응용매로 이용하여 60 내지 150℃에서 반응을 진행하고, 수득율을 분석하였다. 분석결과, 반응온도가 증가할수록 소듐 라우릴옥시벤젠술포네이트 또는 소듐 노나노일옥시벤젠술포네이트의 수득율이 감소하는 것을 확인하였으며, 150℃에서는 반응이 진행되지 않음을 확인하였다.In order to compare the yield of sodium lauryloxybenzenesulfonate or sodium nonanoyloxybenzenesulfonate according to the reaction temperature in one embodiment of the present invention, distilled water is used as a reaction solvent to proceed the reaction at 60 to 150°C, The yield was analyzed. As a result of the analysis, it was confirmed that the yield of sodium lauryloxybenzenesulfonate or sodium nonanoyloxybenzenesulfonate decreased as the reaction temperature increased, and the reaction did not proceed at 150°C.

상기 반응기의 온도가 10℃ 미만인 경우, 반응이 속도가 느려지며, 생성되는 부반응물이 많아져 수득율이 떨어질 수 있으며, 40℃ 초과인 경우, 반응속도는 빠르나 아실클로라이드가 쉽게 분해되어 soap가 많이 생성되어 수득율이 떨어지거나 또는 반응이 진행되지 않는 문제가 발생한다.When the temperature of the reactor is less than 10°C, the reaction is slow, and the number of side reaction products generated increases, so the yield may drop. If it is more than 40°C, the reaction rate is fast, but acyl chloride is easily decomposed and soap is generated more There is a problem that the yield is lowered or the reaction does not proceed.

When the pH is more than 9, there is a problem in that side reaction products generated increase as the reaction with the acyl chloride and sodium hydroxybenzene sulfonate becomes slow.
상기 반응시키는 단계에서 상기 아실클로라이드와 상기 소듐하이드록시벤젠술포네이트가 0.8 내지 1.0: 1.0 내지 1.2의 몰비로 첨가하여 반응시키는 것일 수 있다. In the reacting step, the acyl chloride and the sodium hydroxybenzene sulfonate may be reacted by adding in a molar ratio of 0.8 to 1.0: 1.0 to 1.2.

At this time, the temperature of the reactor was maintained at 28°C. When the dropping of lauryl chloride was completed, the reaction was performed for 1 hour while maintaining the internal temperature of the reactor at 28°C. The pH inside the reactor was checked to keep it below 7, and when the pH was below 7, a small amount of 50% sodium hydroxide was added to adjust the pH to 7-9.
얇은층 크로마토그래피(Thin Layer Chromatography, TLC)로 반응 유무를 확인한 후, 잔류하는 소듐하이드록시벤젠술포네이트가 없을 경우, 반응기에 증류수 300㎖를 투입하여 30분 정도 교반하고, 필터로 여과하였다. 필터로 여과된 합성물을 110℃에서 건조하여 4-Lauroyloxybenzenesulfonate sodium를 수득하였다. After confirming the presence or absence of the reaction by thin layer chromatography (ThLC), if there is no residual sodium hydroxybenzene sulfonate, 300 ml of distilled water is added to the reactor and stirred for 30 minutes, and filtered through a filter. The filtered product was dried at 110°C to obtain 4-Lauroyloxybenzenesulfonate sodium.
