摘要: Abstract The stability of W/O type emulsions the cyclohexane-water system stabilized with polyoxythylene nonylphenylether was studied as a function temperature and hydrophilic chain length emulsifier. interfacial tension same also temperature. It found that: (1) between water oil phases changes markedly becomes nearly zero (below 0.01 dyne/cm) close to phase inversion (PIT); (2) mean droplet diameter is small at PIT but increases temperature; (3) coalescence rate emulsion droplets very fast PIT. Relatively stable were obtained when PIT's are about 10°–40°C lower than storage
