POLY(STYRENE-CO-VINYLBENZYL CHLORIDE-CO-DIVINYLBENZENE) - Introduction
MERRIFIELD RESIN, also known as MERRIFIELD RESIN solution (Mayer's reagent), is a commonly used chemical reagent that has a wide range of applications in chemical analysis.
Properties of MERRIFIELD RESIN:
-Appearance: Usually presented as a colorless or light yellow liquid.
-Ingredients: Mainly composed of potassium ferrate (K2HgI4) and potassium iodide (KI).
-Solubility: Soluble in water.
Use of MERRIFIELD RESIN:
-As a reagent for determining sulfide ions (S2-), it can generate a dark brown precipitate for detecting the presence of sulfide ions.
-In the detection of ketones and ketone-containing compounds, MERRIFIELD RESIN can react with ketones to form red precipitates for qualitative analysis of ketones.
preparation method of MERRIFIELD RESIN:
1. Take appropriate amount of potassium ferrate (K2HgI4) and potassium iodide (KI).
2. Dissolve the two in an appropriate amount of water and stir evenly.
Safety information for MERRIFIELD RESIN:
- MERRIFIELD RESIN contains mercury compounds and should therefore be used with caution.
-in the process of operation to avoid inhalation of its vapor or contact with skin and eyes, such as accidental contact, should immediately rinse with plenty of water.
-Storage should be sealed to avoid mixing with other chemicals.
Please note that MERRIFIELD RESIN has certain toxicity and danger. When used, it should be operated in strict accordance with laboratory safety regulations and follow the guidance of laboratory management personnel.
