Abstract
วิธีผลิตกรดพอลิแลคติกที่สามารถผลิตผลึกของกรดแลคติกซึ่งมีระดับความบริสุทธิ์ซึ่งมี สมบัติแยกของแข็งของเหลวที่ดีเยี่ยมอย่างเสถียร และสามารถผลิตกรดพอลิแลคติกที่มีค่า ลักษณะจำเพาะที่ดีเยี่ยม โดยการผลิตกรดพอลิแลคติกโดยมีกรดแลคติกที่ได้เป็นวัตถุดิบ จากการ นำเข้ากระบวนการเก็บคืนจากฝั่งที่กรองผ่านที่นำสารละลายที่มีกรดแลคติกผสมอยู่ผ่านเยื่อกรอง ระกับนาโนเมตรและกระบวนการเก็บคืนจากฝั่นไอน้ำโดยกลั่นสารละลายกรดแลคติก โดยมี กระบวนการขั้นต้นที่เก็บคืนผลึกของกรดแลคติกที่ทำให้บริสุทธิ์โดยตกผลึกกรดแลคติก A method for producing polylactic acid that can produce lactic acid crystals with purity levels that are Excellent solid-liquid separation properties And can produce valuable polylactic acid Excellent specifications This is done by producing polylactic acid with lactic acid obtained as raw material from the process of retrieval from the filter side through which the solution containing lactic acid is mixed through the membrane. With nanometer and steam retrieval process by distillation of lactic acid solution with a preliminary process that retrieves crystals of lactic acid purified by lactic acid crystallization.
