Okey, sorry for you.
In spite of our responsibility of the global heathing, I think people are getting frustrated about the invironmental issue. Some people with power in political possition, seem to got a panic about it. The most of them, should know, learn, or get the information about from were, or how manufactorers devellope the Nitrometane?
The numbers of modelboat or modelcar drivers are so low. In comparison with for example, anually driven cars, aviation traffic or other user of different chemical products, is the use of petrol in modelsport redicoulesly small.
But the politicians do´nt stop flying, or driving their cars - do they?
Read this för example; When manufactoring Nitrometane, the "Propane" is a part of the process.
"Propane is a three-carbon alkane, normally a gas, but compressible to a transportable liquid. It is derived from other petroleum products during oil or natural gas processing. It is commonly used as a fuel for engines, barbecues, portable stoves and residential central heating.
When used as vehicle fuel, it is commonly known as liquified petroleum gas (LPG or LP-gas), which can be a mixture of propane along with small amounts of propylene, butane, and butylene. The odorant ethanethiol is also added so that people can easily smell the gas in case of a leak."
I´m not very good in chemistry, but a lot makes me really confused in this matter?
By the way - we´re out of topic here!
