Abstract

Sodium dodecanoyl-4-oxybenzenesulfonate (DOBS) salt is a substance that exhibits effective bleaching and antimicrobial abilities at low temperatures. A mild and efficient synthesis method of DOBS starting from dodecanoyl chloride and sodium 4-hydroxybenzene sulfonate was investigated under alkaline conditions using a water (W)-polar aprotic solvent system. First, the reaction was carried out using only water as a solvent system with the variables of temperature and time. The yield was found to be as low as about 5% in most cases under the reaction conditions of more than 30 ℃ and 1 h. In order to develop an efficient solvent system, the effect on the yield of DOBS was evaluated in various solvent systems which were prepared by changing the type of polar aprotic solvents while mixing them with the water. A solvent system in which acetone (AC) and water were mixed showed the best yield and about 82 % under mild reaction conditions (30 ℃, 1 h and atmospheric pressure) was obtained. The prepared DOBS showed good bleaching and antimicrobial activities indicating that it could be used an excellent bleach activator.

4-도데카노일옥시벤젠술폰산나트륨(sodium dodecanoyl-4-oxybenzenesulfonate; DOBS) 염은 저온에서도 효과적인 표백력과 살균력을 나타내는 물질이다. 본 연구에서는 물(W)-극성 비양자성 용매 계를 사용하는 알칼리 조건하에서 dodecanoyl chloride와 sodium 4-hydroxybenzene sulfonate로부터 DOBS의 온화하고 효율적인 합성방법을 조사하였다. 먼저 물만을 용매로 사용하고 온도 또는 시간을 변화시키며 반응한 결과, 수율은 30 ℃와 1 h 이상의 반응 조건에서 대부분 약 5% 정도로 낮게 나타났다. 효율적인 용매 계를 발견하기 위하여 극성 비양자성 용매의 종류를 변화시키며 물과 혼합하여 제조한 다양한 용매계에서 수율에 미치는 영향을 평가하였다. 수율은 아세톤(acetone; AC)과 물을 혼합한 용매 계에서 가장 우수하였으며, 온화한 반응조건(30 ℃, 1 h 및 상압)의 반응에서 약 82%의 높은 값을 나타냈다. 제조한 DOBS는 높은 표백력 및 살균력을 보여 표백활성화제로서 활용이 가능함을 확인하였다.
