Re: 2,2,4 trimethylpentane (Isopar C) - usage and health & safety information
2,2,4-trimethylpentane is in gasoline -- sometimes as much as 10% of gas is
2,2,4-trimethylpentane. Unless things have changed...
HSDB says that besides the uses Mike mentioned, it's a chemical
intermediary. I don't think it's produced in amounts much over a million
pounds a year, and the amount found in gasoline would dwarf this production
