Abstract
ได้เปิดเผยถึงกระบวนการสำหรับทำให้เกิดอีเธอร์ขึ้นแบบแห้งในแป้งลักษณะเม็ด กระบวนการนี้ทำขึ้นโดยมีสารเร่งปฏิกิริยาที่เป็นด่างและน้ำอยู่ด้วย และมีกรดอินทรีย์ในรูปของแข็งอยู่ด้วย ซึ่งกรดอินทรีย์นี้มีการละลายที่ 25 ซง เป็นตั้งแต่ 0.2 ถึง 5 กรัม ในน้ำ 100 กรัม ตัวอย่างของกรดอินทรีย์ที่เหมาะสมคือ กรดฟูมาริค และกรดอะดิพิค Has disclosed the process for the formation of ether dry in granular starches. The process is performed in the presence of alkaline catalysts and water. And contains organic acids in solid form. This organic acid dissolves at 25, from 0.2 to 5 grams in 100 grams of water. Examples of suitable organic acids are fumic acid and adipic acid.
