Preparation method and application of phenol anti-crystallization agent

The invention provides a preparation method and application of a phenol anti-crystallization agent, belongs to the technical field of organic synthesis, and discloses a preparation method of a phenol anti-crystallization agent and a method for preventing phenol crystallization of the phenol anti-crystallization agent. And maintaining the pH value of the system in a range of 1-3, uniformly stirring, and fully cooling to obtain the phenol anti-crystallization agent. By using the phenol anti-crystallization agent, the anti-crystallization time of common fused phenol at the ambient temperature can be 48-60 hours. Compared with biphenyl phenolic resin prepared from common phenol, the biphenyl phenolic resin prepared from the phenol not easy to crystallize has lower viscosity characteristic under the condition of same heat resistance, can greatly reduce the energy consumption in industrial production, and is widely applied to various organic chemical industry fields. 本发明提供一种苯酚抗结晶剂的制备方法及应用，属于有机合成技术领域，公开了一种苯酚抗结晶剂的制备方
