Beschreibung
Zusammenfassung:	FIELD: chemistry. ^ SUBSTANCE: invention refers to method of prepolyester production in tubular etherification reactor. Described method of prepolyester production includes interaction of initial reagents in tubular reactor. In tubular reactor including at least one straight pipe joint and at least one pipe joint, liquid and vapour two-phase reaction mixture flows through at least one segment of specified straight pipe joint. Reduced liquid velocity of liquid and vapour two-phase flow does not exceed approximately 0.15 m/s, while that of vapour thereof is less than approximately 3.0 m/s. ^ EFFECT: production of end product with conversion about 95%. ^ 22 cl, 1 dwg, 5 tbl, 4 ex
