Step-by-step solution

β  -propiolactone uses

There are various uses of beta –propiolactone they are as follows;

$\mathbf{\beta }$-propiolactone is used in the vaccination. Also for the surgical instruments and enzymes as a sterilant of blood plasma,water, and milk.

Preparation of  β -propiolactone

In this reaction $\text{NaOH}$ act as a base so that ${}^{\text{-}}\text{OH}$ attack the carbon next to oxygen so that ring gets open and we get the polymer beta propiolactone.

The mechanism of the reaction is as follows;
