Abstract
การประดิษฐ์ให้กรรมวิธีที่สามารถผลิตเกลือที่ละลายน้ำได้ของแนฟธาลีนซัลโฟเนท ฟอร์แมลดีไฮด์ คอนเดนเซทที่มีปริมาณลดลงของฟอร์แมลดีไฮด์ที่ไม่เกิดปฏิกิริยาได้ง่าย เมื่อ แนฟธาลีนซัลโฟนิค แอซิดถูกนำมายังปฏิกิริยากลั่นตัวกับฟอร์แมลดีไฮด์เพื่อผลิตแนฟธาลีนซัลโฟ เนท ฟอร์แมลดีไฮด์ คอนเดนเซท, เติมซัลไฟท์ลงในระบบปฏิกิริยาหลังจากสิ้นสุดปฏิกิริยากลั่นตัว เมื่อทำให้ได้สารผสมช่วยให้ซีเมนท์กระจายตัว, กรรมวิธีรวมถึงขั้นตอนการทำคอนเดนเซทให้เป็น กลาง The invention provides a process capable of producing naphthalene sulfonate soluble salts. Formaldehyde Condensate with reduced amounts of non-reactive formaldehyde when naphthalene sulfonic The acid was introduced into the distillation reaction with formaldehyde to produce naphthalene, sulfonate, formaldehyde condensate, adding sulfite to the system. Reaction after the end of the condensing reaction When making a mixture to help the cement disperse, the process including the condensate is neutralized.
