Sourcing  This color is fully synthetically made from a mixture of N, N-Diethylaniline and 3-Hydroxybenzaldehyde.
Manufacturing To create Patent Blue V, the N, N-Diethylaniline and 3-Hydroxybenzaldehyde first undergo condensation and sulphonation in acidic conditions of Sulphuric Acid (TLC tested). The outcome (leuco form) of that is treated with Ammonia and then, oxidated with Manganese Dioxide whilst in Phosphoric Acid (HPLC controlled). The outcome of that gets coupled with Sodium Hydroxide. After that, it gets precipitated either by using Hydrochloric Acid and Calcium Chloride or Sodium Chloride and Hydrochloric Acid (UV controlled). The outcome of that gets filtrated and dried at 180°C. It’s then grinded or milled and standardized with either Sodium Sulphate or Sodium Chloride (to 90%).
