When did Thomas Midgley invent freon?

Midgley led the scientific team that in 1928 developed a non-toxic and non-flammable refrigerant called dichlorodifluoromethane, the very first of the chlorofluorocarbons (CFCs), which was sold under the brand name Freon-12.

Was Thomas Midgley married?

On August 'A, 1911, Midgley married Miss Carrie M. Rey- nolds of Delaware, Ohio. Two children were born to them, Jane (Mrs. Edward Z.

What did Mary Midgley believe?

Midgley strongly opposed reductionism and scientism, and argued against any attempt to make science a substitute for the humanities. She wrote extensively about what she thought philosophers can learn from nature, particularly from animals.

Which country banned chlorofluorocarbons?

China ratified the treaty in 1991. According to CNN, a global ban on the use of CFCs has been in place since 2010.

What problem did Thomas Midgley inadvertently create when he developed Chlorofluorocarbons CFCs for use as refrigerants?

First, as a chemical engineer for General Motors, Midgley discovered that the addition of tetraethyl lead to gasoline solved the problem of engine “knocking.” The discovery gave Midgley severe lead poisoning, as Smithsonian has written about previously, and made GM millions of dollars while substantially damaging the ...

Who discovered ozone gas?

Christian Friedrich Schönbein Ozone is a naturally occurring substance which was first made in the laboratory in 1839 by German scientist Christian Friedrich Schönbein (1840a, 1840b). Schönbein was interest- ed in discovering the origin of the odour produced by certain chemical and electrical processes.

Who invented R 12?

CFCs, or chloroflurocarbons, were the first refrigerants that saw mainstream use through the world. The first of it's kind was R-12 that was invented in the early 20th century by General Motors & DuPont. It began widespread usage in the 1920s and was the primary refrigerant for all applications up until the 1950s.

What did Midgley invent for refrigerators?

In the 1930s Midgley developed a non-poisonous substance called CFC (chlorinated fluorocarbon) for use in refrigerators, inhalers and aerosol spray cans. He was given many high awards for his work and in 1944 he became president and chairman of the American Chemical Society.

How many people died because of Thomas Midgley?

Five workers Five workers died from lead poisoning at the Bayway plant in New Jersey, and 35 were hospitalized, many of them driven insane by the neurological effects of lead—”the patient becomes violently maniacal, shouting, leaping from the bed, smashing furniture and acting as if in delirium tremens” one report recorded.

Is Philippa Foot a utilitarian?

Philippa Foot Attacks Utilitarianism as a moral theory. Utilitarianism is a particular form of Consequentialism, and as such it is radically flawed; depending as it does on a vacuous use of expressions such as 'best state of affairs.

What is wrong with moral isolationism According to Midgley?

Midgley thinks that moral reasoning is impossible if we can't understand our own culture. If we can't understand our own culture, then we can't reason, and then we can't give ourselves moral guidance in our own lives. We need moral reasoning to survive, so moral isolationism is wrong.

Is CFC still used today?

Today, the use of CFCs is outlawed by 197 countries around the world and scientists concur that the ozone layer is slowly recovering as a result.

What is CFCs?

Chlorofluorocarbons (CFCs) are nontoxic, nonflammable chemicals containing atoms of carbon, chlorine, and fluorine. They are used in the manufacture of aerosol sprays, blowing agents for foams and packing materials, as solvents, and as refrigerants. ... Individual CFC molecules are labeled with a unique numbering system.

What is ozone smell?

Some people think that ozone is the scent that fills the air right after heavy rain or a thunderstorm. The smell of ozone reminds some of the chlorine, metal, burnt wire. Most people can detect approximately 0.01 mol of ozone in the air, thanks to its rather pungent odor.

How do you make O3?

Ozone (O3) is created when diatomic oxygen (O2) is exposed to an electrical field or ultraviolet (UV) light. Exposure to these high levels of energy causes a portion of the diatomic oxygen molecules to split into individual oxygen atoms. These free oxygen atoms combine with diatomic oxygen molecules to form ozone.

What is Puron refrigerant?

Puron refrigerant, also known as R410A, is a chemical used to create refrigerated air in homes and commercial buildings. Unlike other refrigerants, Puron has numerous advantages for the New Jersey homeowner and also for the environment.

Is R-12 Freon illegal?

R-12 is a colorless and odorless CFC refrigerant that was completely banned from production by 1996 under the Montreal Protocol for depleting the ozone.
