Definition

1. Noun:
   • A chemical process involving decomposition by heat: "destructive distillation" refers to the process of heating an organic material in the absence of air or in a closed container to break it down, producing volatile substances which are then condensed and collected.

Usage

• Noun:
  • Destructive distillation of wood produces charcoal, methanol, and other chemicals.
  • The laboratory experiment involved the destructive distillation of coal to obtain various hydrocarbon products.

Advanced Usage

• Technical/Industrial Context: The term is primarily used in chemistry, chemical engineering, and industrial manufacturing to describe a specific pyrolysis process for obtaining useful products from raw materials like coal, wood, or oil shale.
  • The plant uses destructive distillation to convert bituminous coal into coke and coal tar.

Variants and Related Words

• Pyrolysis (n): The thermal decomposition of materials at elevated temperatures in an inert atmosphere. Destructive distillation is a specific type of pyrolysis conducted in a closed system to collect the volatile fractions.
• Carbonization (n): A process often resulting from destructive distillation, where organic substances are converted into carbon or a carbon-containing residue.

Synonyms

• Decomposing distillation: A less common synonym emphasizing the breakdown aspect.
• Dry distillation: An older term sometimes used interchangeably, though it can have a broader meaning.

Related Phrases

• To undergo destructive distillation: Describes the material being processed.
  • The organic matter will undergo destructive distillation in the retort.

Noun

1. heating a solid substance in a closed container and collecting the volatile products
