pH of 99.9% pure tetrahydrofuran is around 4.5 - 5.0 (Sigma-Aldrich)
yes
yes.
Tetrahydrofuran, otherwise known as THF or (CH2)4O, has a dipole moment of 1.1 D because of the single oxygen atoms placement in the ring,.
Mineral oil is a nonpolar compound. Water and tetrahydrofuran are both polar compounds. Polar compounds and nonpolar compounds do not generally mix.
A solvent for CPVC contain mostly tetrahydrofuran and acetone, cyclohexanone, chloroethene.
