Technology Process of Talc

There total 14 articles about Talc which guide to synthetic route it. The literature collected by LookChem mainly comes from the sharing of users and the free literature resources found by Internet computing technology. We keep the original model of the professional version of literature to make it easier and faster for users to retrieve and use. At the same time, we analyze and calculate the most feasible synthesis route with the highest yield for your reference as below:

synthetic route:

Reference yield: 30.0%

→ magnesium silicate (14807-96-6)

Guidance literature:

Reference yield:

→ magnesium silicate (14807-96-6) + magnesium stearate (557-04-0)

Guidance literature:

Reference yield:

magnesium(II) nitrate (13446-18-9) + silica gel (112926-00-8,7631-86-9) → magnesium silicate (14807-96-6)

Guidance literature:

With KOH; In melt; Mg(NO3)2 was added to an eutectic melt of KNO3/LiNO3 at 350 °C, followed by a melt of SiO2 in KOH;; the pptd. prod. was either isolated by filtration of the melt through a layer of compressed quartz powder or by leaching the cooled mass with water, alcohol, or acetone;

upstream raw materials:

magnesium(II) nitrate

silica gel

magnesium chloride

Downstream raw materials:

water

silica gel
