2-Amino-3-hydroxypyridine (CAS # 16867-03-1) Kev taw qhia

2-Amino-3-hydroxypyridine. Cov hauv qab no yog kev qhia txog nws cov khoom, kev siv, kev tsim khoom thiab cov ntaub ntawv kev nyab xeeb:

Zoo:
2-Amino-3-hydroxypyridine yog ib qho organic compound nrog lub ntsej muag dawb crystalline uas yog soluble hauv dej thiab qee cov kuab tshuaj organic.
Nws yog lub hauv paus muaj zog uas neutralizes acids thiab tsim cov ntsev sib xws. Nws muaj pH siab thiab feem ntau siv rau hauv cov tshuaj tiv thaiv neutralization.

Kev Siv: Nws kuj tuaj yeem siv rau hauv kev npaj ntau yam khoom siv tshuaj xws li dyes, coatings, thiab softeners.

Txoj kev:
Kev npaj ntawm 2-amino-3-hydroxypyridine feem ntau pib los ntawm pyridine. Ua ntej, pyridine yog reacted nrog ammonia roj los ua 2-aminopyridine. Tom qab ntawd, nyob rau hauv lub xub ntiag ntawm sodium hydroxide, cov tshuaj tiv thaiv yog tsim los ua 2-amino-3-hydroxypyridine.

Cov ntaub ntawv kev nyab xeeb:
2-Amino-3-hydroxypyridine tej zaum yuav muaj kev cuam tshuam rau lub qhov muag, tawv nqaij, thiab ua pa. Thaum siv, thov tswj kev tiv thaiv kom tsim nyog, xws li hnav hnab looj tes, tsom iav kev nyab xeeb, thiab lwm yam. Thov khaws cov khoom sib xyaw kom zoo, kom deb ntawm cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob.
