原料药的破坏实验怎么做?谢谢
我现在在做原料药的破坏实验,不同药物的破坏条件不同吗?破坏到哪种程度才可以呢?谢谢!!!
请问一下 酸碱破坏都得在水浴中加热一下吗?加热多长时间呢?谢谢
那请问一下 降解时候条件的最大限度是多少呢?我以前做实验的时候就是随便做的,酸碱的浓度很大,报着一定要破坏出来的心态,非常感谢!!!:)
要根据你原料的结构来定,如果酸中极易降解那不需要水浴,有的原料易氧化加双氧水后要立即定容进样的,具体结构具体分析,不能一概而论。
我也只是培训知道,主要在做制剂。如同其他同仁说得不错,要看原料物理化学性质,不能一概而论,只要达到相应结果即可,不必纠结时间温度等具体参数。

The equilibrium constant K p for the dissociation reaction of the gas A 2 A 2 ( g) ↔ 2 A ( g) was measured as a function of temperature (in K). A graph of lnK p versus 1/T for this reaction gives a straight line with a slope of -1.722x 10 4 and an intercept of 13.83. Calculate the value of ΔS in J mol -1 K -1 for this reaction.
The solubility of O 2 in water is 0.601 g/L at an oxygen pressure of 15.38 atm. What is the Henry's law constant k H for oxygen in units of mol L -1 atm -1? Q12
Calculate Kp for the reaction H2O2 (g)
↔ H2O (g) + 1/2 O2 (g), using the following data:H2 (g) + O2 (g) ↔ H2O2 (g )Kp= 7.865x 1062 H2 (g) + O2 (g) &#O (g) Kp= 8.847x 1036Q13
For a certain reaction at 30°C the value of K is 1.5 x 10-3. At 60°C the value of K is 2.7x10-1.This means that the reaction is...Answer
a. more information is needed to find a correct answer.
b. ...exothermic.
c. ...endothermic.
d. always favourable.
e. never favourable. 14 A 3L flask initially contains 1.523 mol of gas A and 0.4449 mol of gas B. Gas A decomposes according to the following equation:3 A ↔ 2 B + C The equilibrium concentration of gas C is 0.1 mol/L.Calculate the value of Kc. Q15
The reaction H 2 ( g) + I 2 ( g) ↔ 2 HI ( g) has a K p=45.9 at 763 K. A particular equilibrium mixture at that temperature contains gaseous HI at a partial pressure of 3.671 atm and hydrogen gas at a partial pressure of 1.101 atm. What is the partial pressure of I 2 in Pa?
