Paraffins
Paraffins
Paraffins (pronunciation: /ˈparəfin/), also known as alkanes, are a group of hydrocarbons with the general formula CnH2n+2. The term "paraffin" is derived from the Latin words "parum" (meaning "little") and "affinis" (meaning "affinity"), indicating the minimal reactivity of these compounds.
Etymology
The term "paraffin" was first used in the mid-19th century and is attributed to the German chemist Karl von Reichenbach. He derived the term from the Latin words "parum" and "affinis", reflecting the low reactivity of these hydrocarbons.
Types of Paraffins
Paraffins can be classified into two main types:
- Normal paraffins: These are straight-chain hydrocarbons. An example is hexane.
- Iso-paraffins: These are branched-chain hydrocarbons. An example is isooctane.
Uses of Paraffins
Paraffins have a wide range of uses in various industries. They are used in the production of lubricants, waxes, and as a fuel source in heating appliances. In the medical field, paraffin wax is used in physiotherapy for heat treatments.
Health Effects
Exposure to paraffins can have several health effects. Inhalation can cause respiratory problems, while skin contact can lead to dermatitis. Ingestion can result in gastrointestinal issues.
