cis 1,4-dichloro-2-butene:
At 69°C and pH 7.16 a half-life of 0.02 days was determined. With a  hydrolysis rate constant of 9.1E-03 +/- 1.1 at pH 7 a half-life of 3.2  days at 25°C is calculated.
trans 1,4-dichloro-2-butene:
At 69°C and pH 9.90 a half-life of 0.02 days was determined. With a  hydrolysis rate constant of 9.0E-03 +/- 0.5 at pH 7 a half-life of 3.2  days at 25°C is calculated
