"Organics and Organic Synthetic Materials" PPT courseware

Part One: Some Simple Organic Compounds

1. The concept of organic matter

(1) Compounds containing carbon are usually called organic compounds, or organic matter for short.

Corresponding to organic matter is inorganic matter, which includes elements and inorganic compounds.

(2) Carbon oxides, carbonic acid, and carbonates are carbon-containing compounds, but because they are similar to inorganic compounds in structure, composition, and properties, they are usually classified as inorganic substances.

(3) Most organic matter contains elements such as _____, _____, _____, _____.

2. Methane.

(1) The chemical formula of methane is CH4, which is the simplest organic compound.

Straw and animal manure will also produce a large amount of biogas after fermentation, which is often used as fuel for heating in rural areas.

(2) The main components of biogas, natural gas and petroleum gas are methane. There is also a lot of methane in the atmosphere of Mars

Phenomenon: a blue flame is produced and the lime water becomes turbid.

(3) Methane is flammable. The combustion products are _____ and _____. The chemical equation of combustion is CH2+2O2 == CO2+2H2O.

Organic matter and organic synthetic materials PPT, Part 2 content: Organic matter of great significance to life activities

1. Organic matter is the main component of various tissues of living organisms. The growth and development of the human body and the metabolism of various tissues in the body require the participation of various organic substances.

2. The most basic organic compounds in the human body include ______, ______, ___, etc.

(1) Sugar is the main source of energy consumed by the human body (energy supply substance), and it is also the raw material for the synthesis of many important compounds in the human body. Common sugars include glucose (monosaccharide), fructose, sucrose, maltose, and lactose. The simplest sugar is glucose (C6H12O6).

(2) Proteins are the basic substances that constitute living organisms. Proteins are the most complex and changeable type of macromolecules in cellular structures. The relative molecular weight is approximately between 1.2 and 1 million. Protein is composed of four elements: C, H, O, and N.

Organic matter and organic synthetic materials PPT, Part 3: Organic synthetic materials

1. Three major organic synthetic materials: plastics, synthetic rubber, and synthetic fibers.

2. Properties of plastic: It has plasticity. When heated to a certain temperature, plastic can melt into a viscous liquid and can be made into products of various shapes after cooling. Plastic is light and strong, easy to process, stable in nature and has good insulation properties. However, because plastic has a stable structure and is not easy to decompose, it will cause serious environmental pollution - "white pollution".

3. Synthetic fibers are artificially synthesized from petrochemical products as the main raw materials. Different varieties of synthetic fibers have their own unique properties. It is widely used in the manufacture of insulation materials, special protective materials, reinforcement materials for spacecraft, aircraft, rockets, missiles, artificial heart valves, surgical sutures, etc.

4. Synthetic rubber is a highly elastic polymer artificially synthesized from coal, petroleum, and natural gas as the main raw materials. It has high elasticity, insulation, air tightness, oil resistance, high temperature or low temperature resistance, and is therefore widely used in agriculture, national defense, and transportation. and daily life.

5. Natural gas is one of the most important energy sources in the world today. Its main component is chemical formula ______. When natural gas is mixed with oxygen, ______ may occur when ignited, so ______ should be done before igniting.

6. Organic compounds that are of great significance to life activities are mainly ______, ______, _____, etc. Among them, protein is the basic substance that constitutes the living body, ______ is the main substance that the human body consumes energy, and ______ exists in the body in the form of storing energy.
