Special techniques were developed for making these measurements. It is known for being a major component of plastic soda bottles, detergent bottles, bottles for various household cleaners and makeup. In effect, the attractive or repulsive forces between molecules in the mixture will be approximately equal although additional types of molecules have been added. p-xylene, ethyl-ether, i-propyl ether, pyridine, chloroform, ethyl-ethyl ketone, carbon tetra- . such as water, methanol, and other alcohols increase the rate still more dramatically when added to the DMA/ether mixtures. To understand this, we would need to see what type of interaction sulfur and water undergo respectively. Other non-polar solvents will dissolve it to some extent. Areas of application include the printing, rubber, and leather industries. [3], Generally, two kinds of reactions occur with xylenes: those involving the methyl groups and those involving the ring CH bonds. p-Xylene is the principal precursor to terephthalic acid and dimethyl terephthalate, both monomers used in the production of polyethylene terephthalate (PET) plastic bottles and polyester clothing.
