例句
The preservative used is usually ethylene glycol or propylene glycol, as alcohol will evaporate quickly and the traps will dry out.
常用防腐剂是乙二醇或丙二醇，因为随着酒精快速挥发，捕集器也随之恢复干燥。
That too means less propylene, since it is also a by-product of petrol production.
既然丙烯也是石油工业产品的副产物，这也意味着其产量缩水。
The trouble is that the ethane route to making ethylene produces virtually no propylene.
问题在于这种用乙烷制作乙烯的生产流程几乎不会伴有丙烯产生。

Well, let's just take one example.Fifty percent of the world's production of propylene oxideis made through the chlor-alkali process.
So that's five million tons of salt mined from the earthconverted through the chlor-alkali process into propylene oxide,and then during that process,
that are created from whatever is in the e-liquid.So an aerosol could contain propylene glycol and glycerin,which are solvents in the e-liquid.
is made through the chlor-alkali process.And that's a total of about five million tons of propylene oxideon an annual basis, made globally.
