Abstract
A water/butoxyethanol solution has been investigated by means of sever al techniques (viscosity, ultrasound and hypersound) as a function of concentration and temperature. The butoxyethanol molar fraction range investigated was situated between 0.015 and 0.09, while temperature ra nged between -10 degrees C and +45 degrees C. We observed the building -up of large structures lowering the temperature, in particular below +15 degrees C. Ah data coming from different techniques seem to confir m such a picture and indicate that this aggregation phenomenon is a pe rcolation-like process.
