Abstract
กระบวนการสำหรับเตรียมโลหะอัลคาไลน์เอิร์ธที่ได้ซัลเฟอไรซ์แล้ว โดยเฉพาะอย่างยิ่ง แคลเซียมแอลคิลฟีเนต โดยการทำ ให้แอลคิลฟีนอลที่ได้ซัลเฟอไรซ์แล้วเป็นกลางด้วยเบสของโลหะ อัลคาไลน์เอิร์ธ (เป็นต้นว่า ปูนขาว) เมื่อมีน้ำมัน กลัยคอล แอลกอฮอล์ที่มีจุดเดือดสูงกว่า 150 ํซ และไอออน ของเฮไลด์อยู่ด้วย การกลั่นและการกรองและคาร์บอเนชัน ที่ตามด้วยการกลั่นและการกรอง ผลิตภัณฑ์ที่ได้จะสามารถใช้เป็น สารเติมผสมประเภทสารช่วยกระจาย-รักษาความสะอาดที่มีสภาวะ ความเป็นด่างสูงสำหรับน้ำมันหล่อลื่น Process for the preparation of sulfurized alkaline earth metals Especially Calcium Alkylphenate by neutralizing the sulfurized alkylphenol with a metal base. Alkaline earth (eg lime) when there is oil, glycol, alcohol with a boiling point above 150 ํ and halide ions. Distillation and Filtration and Carbonation Followed by distillation and filtration. The resulting product can be used as Dispersant type additive - Maintain the cleanliness conditions. High alkalinity for lubricants
