Description

"Organic Synthetic Materials" Chemistry and Life PPT Courseware 2

learning target

Know what organic matter is and understand the classification of organic polymer materials.

Understand the characteristics, uses and impact of organic synthetic materials on the environment, and understand the importance of environmental protection.

Cultivate your own self-learning ability, thinking ability and expression ability, and develop the ability of scientific inquiry.

Organic compounds: Compounds containing carbon elements such as methane and ethanol are called organic compounds.

Inorganic compounds: Compounds that do not contain carbon such as sodium chloride and sulfuric acid are called inorganic compounds.

Question: What do carbon dioxide, carbonic acid and calcium carbonate belong to?

Debate: Pros and cons of plastic products

Plastic is cheaper to make, durable and waterproof.

Plastic is easily molded into different shapes.

Some plastics burn easily and produce toxic gases when burned.

Most plastics are highly resistant to corrosion and do not react with acids or alkalis.

Most plastics will not rot or be decomposed by bacteria, easily causing "white pollution".

Plastics generally do not conduct heat or electricity and are good insulators.

When recycling waste plastics, sorting them is difficult and economically uneconomical.

Plastics are made from petroleum refining products, and petroleum resources are limited.

How to solve the problem of "white pollution"

Reduce the use of unnecessary plastic products, such as using cloth bags instead of plastic bags.

Reuse certain plastic products such as plastic bags, plastic boxes, etc.

Use some new, degradable plastics, such as microbially degradable plastics and photodegradable plastics.

Classify and recycle various waste plastics.

What did you gain after studying this topic?

All organic compounds contain carbon, but not all compounds containing carbon are organic compounds.

Organic polymer compounds are organic compounds with a large relative molecular mass. Divided into natural organic polymers and organic synthetic materials.

Plastics, synthetic fibers and synthetic rubber are important organic synthetic materials.

The use of organic synthetic materials will have an impact on the environment, such as "white pollution".
