Lactic Acid → 2-(p-Nonylphenoxy)ethanol

Participants

Reaction Steps

In a stainless steel reactor having an inner volume of 1,000 ml and provided with a thermometer, a pressure gauge, and a stirrer, 200 g of nonylphenol (molecular weight 221), 0.6 g of sodium hydroxide as a catalyst, and 400 g of ethylene oxide were heated at 150° C. under pressure of 6.0 kg/cm2G of reaction. The resultant averagely 10-mole ethylene oxide adduct of nonylphenol and 2.7 g of an aqueous 50 wt% lactic acid solution added thereto were thoroughly stirred. The nonylphenol ethoxylate obtained as the result was tested for the effect of aging. The results are shown in Table 27.
