a. What are petrochemicals. Chemicals derived from **petroleum ** or **natural gas ** b. Where do petrochemicals come from? c. What is the fractional distillation d. How do petrochemicals get into the environment? Petrochemicals are found in a wide array of household items, from plastic wrap and trash bags to plastic bottles. Because humans rely so heavily on petrochemicals, their production is high, affecting the environment via oil spills on land and sea and fossil fuel combustion emissions. e. What happens to the petrochemicals, plants, and animals?
 * Petrochemicals **, also called ** petroleum distillates ** , are [|chemical products] derived from [|petroleum] . Some [|chemical compounds] made from petroleum are also obtained from other [|fossil fuels] , such as [|coal] or [|natural gas] , or renewable sources such as [|corn] or [|sugar cane].
 * Fractional distillation ** is the [|separation] of a [|mixture] into its component parts, or [|fractions], separating [|chemical compounds] by their [|boiling point] by heating them to a [|temperature] at which one or more fractions of the compound will [|vaporize] . It uses [|distillation] to [|fractionate] . Generally the component parts have boiling points that differ by less than 25 °C from each other under a pressure of one [|atmosphere] . If the difference in boiling points is greater than 25 °C, a [|simple distillation] is typically used.
