Summary:The present invention relates to a method for producing carnitine orotate using a novel orotate intermediate, and more specifically, to a method for manufacturing high purity carnitine orotate at high yield, wherein a novel ortic acid tertiary amine salt is produced by adding tertiary amines to ortic acid having a low solubility in an organic solvent or purified water, and then an acid-base exchange reaction with carnitine hydrochloride is performed to easily remove impurities in a single reaction solvent without using a separate crystallization solvent. 본 발명은 신규한 오르트산염 중간체를 이용한 카르니틴 오르트산염의 제조방법 에 관한 것으로, 보다 상세하게는 유기용매 또는 정제수에 용해성이 낮은 오르트산에 3차 아민류를 첨가하여 신규한 오르트산 3차 아민염으로 제조한 후, 카르니틴 염산염과의 산염기 교환반응을 수행함으로써, 별도의 결정화 용매를 사용하지 않고도 단일 반응용매 내에서 불순물의 제거가 용이하여 고수율 및 고순도의 카르니틴 오르트산염을 제조할 수 있는 방법에 관한 것이다.
