Talc - Identification of Medicinal Materials
Herbal identification
The talc herbs are flat, rhomboid or irregularly shaped, with varying sizes. All white, egg blue or yellowish white, the surface has a pearl-like luster, translucent or opaque. The quality is soft and meticulous, the hand feels smooth and smooth, and the white powder can be scraped with the fingers. Odorless, tasteless, and slightly cool. It is better to be neat, bluish-white, smooth and free from miscellaneous stones. Microscopic identification: Under the transmission polarizer: colorless and transparent in the sheet. Low projection. The highest interference color up to three orange, some talc maximum interference only reached the second middle. Nearly parallel extinction (sliding angle only 2°-3°). We are extending the symbol. Biaxial crystals. Negative light. The refractive index is Np=1,538-1.550, Nm=1.575-1.594, and the birefringence Ng-Np=0.030-0.050.
1. Identification of silicon: Take about 0.2g of this product powder in a platinum crucible, add equal amount of calcium fluoride (or sodium fluoride) powder, mix well, add concentrated sulfuric acid 5ml, slightly hot, and immediately put a platinum with 1 drop of water Cover the lid, wait for a while, and remove the lid. The water droplets appear white and cloudy.
2. Magnesium identification: take this product powder 0.5g, set the flask, add hydrochloric acid (4 → 10) 10ml, cover the watch glass, heated to micro-boiling, shaking the beaker from time to time and keep the micro-boiling for 40 minutes, remove, with fast filter paper Filter and wash the residue with water 4-5 times. Take about 0.1g residue, placed in the mash, add 10 drops of sulfuric acid (1 → 2) and hydrofluoric acid 5ml, heat decomposition and evaporation to sulfur trioxide white smoke, remove cooling, add 10ml water to dissolve. Draw 2 drops of this solution, add 1 drop of magnesium reagent, add sodium hydroxide solution to make it alkaline, and immediately appear sky blue precipitation.
