Solution
Question 7
1 / -0

Di-n-butylphthalate is:

A
plasticizer

B
thermoplastic

C
polymer

D
thermosetting plastic

Solution

Dibutyl phthalate (DBP) is an organic compound commonly used $$plasticizer$$. With the chemical formula $$C_6H_4(CO_2C_4H_9)_2$$, it is a colorless oil, although commercial samples are often yellow. Because of its low toxicity and wide liquid range, it is used as a plasticizer.
So option $$A$$ is correct.
