On my end, when the pH is adjusted to 6 and continuous distillation is carried out, the pH drops to 4, which results in the formation of tar. What’s going on?

What process, what raw materials? A clear description is needed before we can discuss it
First, the problem wasn’t clearly explained； Second, according to you, the pH value is 6 before entering the distillation tower and 4 after distillation; either there is an acidic substance in the medium that gets purified, or a reaction occurs during the distillation process (such as hydrolysis)
