| titleOfInvention | A kind of preparation method of hydrophobically modified xanthan |
| abstract | The present invention relates to a kind of preparation method of hydrophobically modified xanthan.The method for solvent, is emulsifying agent with ammonium lauryl sulfate with water/Virahol mixed solution, is that etherifying agent obtains hydrophobically modified xanthan in 30 ~ 120 DEG C of temperature, pH6 ~ 9 time reaction to xanthan gum modification with brominated alkanes.This synthetic reaction condition is gentle, raw material is easy to get, and monomer conversion is high, and product process is convenient.Xanthan gum after hydrophobically modified still has higher viscosity when having lower molecular weight, has good salt resistance, good degradability, is convenient to carry out follow-up sewage disposal, has good environment affinity; The oil recovery being applicable to high salinity reservoir is produced. |
