phenacetin 325 mg acetaminophen

 

 

Phenacetin is a prodrug that can be prepared from acetaminophen, a commonly used pain and fever reducer. While available in many parts of the world, phenacetin is not sold in the United States due to concerns about its toxicity. What is the theoretical yield of phenacetin (in grams) upon reaction of 325 mg of acetaminophen? Assume that acetaminophen is the limiting reactant.

▶ 참고: 한계 반응물

---------------------------------------------------

 

▶ phenacetin. 페나세틴

> 화학식: C10H13NO2

> C10H13NO2의 몰질량 = 179.22 g/mol

 

 

 

▶ acetaminophen. 아세트아미노펜

> 화학식: C8H9NO2

> C8H9NO2의 몰질량 = 151.16 g/mol

 

 

 

0.325 g / (151.16 g/mol) = 0.00215 mol acetaminophen

( 참고 https://ywpop.tistory.com/7738 )

 

 

 

acetaminophen : phenacetin = 1 : 1 계수비(= 몰수비) 이므로,

한계 반응물인 acetaminophen이 반응한 몰수

= 생성물 phenacetin의 몰수 = 0.00215 mol

 

 

 

0.00215 mol × (179.22 g/mol) = 0.385 g phenacetin

 

 

 

답: 0.385 g
