原始语种摘要: Abstract(#br)The ability to measure the length of polymers while monitoring their production is evidently extremely valuable, but is also a useful tool for chemical identification purposes at other times, e.g. the analysis of waste water. A study of the relationship between velocity of sound and chain length has been carried out. Initial studies were performed on two model systems; a series of pure liquid n -alkanes (pentane to hexadecane) and 1-alcohols (methanol to 1-dodecanol). This study was extended to look at an industrially significant system of dimethylsiloxanes 200 fluid (L2, 0.65 cSt) to 200 fluid (5000 cSt). Corresponding density data have been taken from the literature and the adiabatic compressibility determined. The measured adiabatic compressibility has been compared with...
