Problems solved by technology

However, the disadvantage of the method described in ZL 200110162138.8 is that the catalyst used is metal oxide and carrier 4A zeolite, which is a heterogeneous catalyst with poor solubility in water, so there is still a possibility of improvement. In addition, the obtained surfactant properties still need further improvement
