A depressor action composition was prepared for lowering the pour point of high‐paraffin oils based on butanol and cotton soap stock fatty acids (FA), mainly a C16–C18 distillate fraction. The possibility of using cotton soap stock FA for their esterification with butyl alcohol and ester production based on them is shown. A scheme for preparing the depressor action reagent “BEG‐1” based on the esterified FA, monoethanolamine, and cotton soap stock is proposed. When the BEG was introduced into the samples of high‐paraffin oil taken directly from the group metering device, a decrease in the paraffin crystal size and shape was observed, i.e. their almost complete dissolution, which was accompanied by a change in the viscosity of the samples. Compositions having high surface‐active properties, thermodynamic resistance, and stability were prepared. The paraffin crystal morphology, crystal structure, and shape change were studied. The data obtained are of value for the pipeline transport of hydrocarbons, as the use of the proposed depressor action reagent for high‐paraffin oils can significantly reduce the viscosity of the oil in the pipeline, helping to reduce the energy costs associated with heating the oil for its pumping.

获得高石蜡含量的抗抑郁药

基于丁醇和棉皂原料脂肪酸（FA）（主要是C16-C18馏分），制备了降压剂组合物以降低高链烷烃油的倾点。示出了使用棉皂原料FA与丁醇进行酯化和基于它们生产酯的可能性。提出了一种基于酯化FA，单乙醇胺和棉皂原料的降压剂“ BEG-1”的制备方案。当将BEG引入直接从群计量装置中取出的高石蜡油样品中时，观察到石蜡晶体尺寸和形状减小，即它们几乎完全溶解，同时伴随着粘度的变化。样品。制备了具有高表面活性，热力学稳定性和稳定性的组合物。研究了石蜡的晶体形态，晶体结构和形状变化。所获得的数据对于碳氢化合物的管道运输具有重要意义，因为针对高链烷烃油使用建议的降压剂可以显着降低管道中石油的粘度，从而有助于降低与加热石油相关的能源成本为其抽水。
