개요약간 의 조해성이 있고 열을 가하면 100℃에서 무수물로 되고 강열하면 메타인산나트륨을 생성한다. 용해 도는 (20℃，112／100水)，(99℃，448／100水)，수용액은 약산성이다. 알코올에는 불용, 클로로포름 에는 약간 녹는다.

용도1. 청 관제 (일반 공업용 보일러) 2. 염색 (염료 분산제) 3. 양모 탈색제 4. 의약 (페니실린, 스 트렙토 마이신의 배양제) 5. 식품 (식육 결착제)

용도Sodium dihydrogen phosphate dihydrate acts as buffering capacity reagent in molecular biology, biochemistry and chromatography. It is used in the preparation of biological buffers. It is also used in the purification of antibodies, as a laxative and, in combination with other sodium phosphates.Sodium phosphate monobasic dihydrate is a reagent with very high buffering capacity widely used in molecular biology, biochemistry and chromatography. Sodium phosphate dibasic is highly hygroscopic and water soluble.Recommended chemicals for the preparation of phosphate buffers are sodium dihydrogen phosphate dihydrate，NaH2PO4.2H2O(mol. wt.156.0)，disodium hydrogen phosphate dihydrate，Na2HPO4.2H2O (mol. wt.178.0), and sodium hydroxide pellets.

제조 방법 · 1건

생산 방법Monobasic sodium phosphate is prepared by adding phosphoric acid to a hot, concentrated solution of disodium phosphate until the liquid ceases to form a precipitate with barium chloride. This solution is then concentrated and the monobasic sodium phosphate is crystallized.
