以直链烷基酚醛树脂为起始剂的聚醚原油破乳剂、其制备方法及其应用
摘要：
本发明公开一种以直链烷基酚醛树脂为起始剂的聚醚原油破乳剂、其制备方法及其应用。以直链烷基酚醛树脂为起始剂的聚醚原油破乳剂，其通式为A-(PO)a-(PO)b-(EO)c-(PO)m，其中PO为-（CH2-O-CH2CH2）-，EO为-（O-CH2CH2）-，A为R为碳数为6-10的直链烷基，n为5-13的整数，a+b=m，通式中EO的质量为PO与EO质量和的15%-25%。本发明制备的聚醚破乳剂制备工艺简单，表面活性好，破乳能力和扩散能力强，具有良好的脱水效果，原油破乳脱水率达80～92%，尤其在改善油水界面乳化性能上表现优异，具有很强的普适性。
摘要（英）：

The invention discloses a polyether crude oil demulsifier using straight chain alkyl phenolic resin as an initiator and a preparation method and application thereof. The general formula of the polyether crude oil demulsifier using straight chain alkyl phenolic resin as an initiator is A-(PO)a-(PO)b-(EO)c-(PO)m, wherein PO is -(CH2-O-CH2CH2)-, EO is -(O-CH2CH2)-, A is shown in the description, and R are straight chain alkyls with carbon number of 6, n is an integer of 5-13, a is equal to m, and in the general formula, the mass of EO accounts for 15-25% of the mass sum of EO and PO. The polyether crude oil demulsifier prepared by the invention is simple in preparation process, good in surface activity, strong in demulsification capability and diffusion capability, good in dehydration effect, especially excellent in capability of perfecting oil-water interface emulsification performance and strong in universality, and the demulsification and dehydration rate of the crude oil reaches to 80-92%.
