Objective:To analyze the factors influencing chloral hydrate stability. Methods: The influences of temperature, the length of time, the ultraviolet ray shines and alkaline materials on chloral hydrate in the mixture were researched with retitration method.Results:It was found that all of these factors had influence on the stability of chloral hydrate. Among them the ultraviolet ray was the most influential.Conclusion: In order to guarantee the chloral hydrate fulfilling requirements within fixed time, It must be used up within stipulated time, and may not be compounded with the hot water.
