Triton X-45, a nonionic surfactant with a low hydrophile-lypophile balance value and dispersible in aqueous solution at room temperature, has a Krafft point above the room temperature. The cloud point of Triton X-45 in an aqueous solution is different from the conventional aqueous nonionic surfactant micelle solution. It was further confirmed by a determination of the effect of additives on the phase behavior of aqueous solutions containing Triton X-45. The experimental fact eliminates the prevalent concept that the cloud point of Triton X-45 is below room temperature, which is helpful to exploit a biocompatible medium for a microbial growth and then for whole cell microbial transformation in a nonaqueous medium.
Triton X - 45是一种亲水亲油平衡值较低的非离子表面活性剂，室温下可分散于水溶液中，其克拉夫特点高于室温。Triton X - 45在水溶液中的浊点与传统的非离子表面活性剂胶束水溶液不同。通过测定添加剂对含Triton X - 45水溶液相行为的影响进一步证实了这一点。这一实验事实消除了普遍认为Triton X - 45浊点低于室温的观念，这有助于开发一种用于微生物生长的生物相容性介质，进而用于非水介质中的全细胞微生物转化。
