The present invention provides a manufacturing method of high purity 2-ethylhexyl glycerol ether which maintains 2-ethylhexyl glycerol ether which is a product of hydrolysis in an appropriate amount range in water used for a hydrolysis and effectively reduces a hydrolysis reaction temperature, thereby effectively reducing production amounts of coloring and sampling impurities difficult to remove in a distillation method. Also, the present invention can increase productivity by increasing a hydrolysis reaction rate. The manufacturing method comprises: a first step of conducting the hydrolysis of the 2-ethylhexyl glycerol ether； a second step of phase-separating the hydrolysis product of the first step into a 2-ethylhexyl glycerol ether layer and a water layer； and a third step of purifying the phase-separated 2-ethylhexyl glycerol ether layer.COPYRIGHT KIPO 2018본 발명은 가수분해 반응에 사용되는 물에 가수분해 생성물인 2-에틸헥실글리세롤에테르를 적정량 범위로 유지하고, 가수분해 반응온도를 효과적으로 낮춤으로써, 증류 방법으로 제거가 어려운 발색, 발취 불순물 생성량을 반응 단계에서 효과적으로 감소시키고, 가수분해 반응속도를 빠르게 하여 생산성을 높일 수 있는 고순도 2-에틸헥실글리세롤에테르 제조방법을 제공한다.
