Description
Chromic acetate, also known as chromium acetate, is a grayish-green to bluish-green powder or pasty mass with chemical properties that make it a versatile compound in various industries. It is primarily recognized for its use as a tanning agent and textile dyeing mordant, while also serving as a catalyst for polymerization and oxidation processes, as well as an emulsion hardener.
Uses
Used in Textile Industry:
Chromic acetate is used as a mordant in the textile industry for dyeing processes. It enhances the colorfastness and quality of dyed fabrics by forming a strong bond between the dye and the textile fibers, ensuring the durability and longevity of the color.
Used in Tanning Industry:
In the tanning industry, chromic acetate is employed as a tanning agent. It helps in the process of converting raw hides and skins into leather by cross-linking the collagen fibers, which results in improved strength, flexibility, and resistance to degradation.
Used in Chemical Industry:
Chromic acetate is used as a catalyst in the chemical industry for various processes, including polymerization and oxidation. Its catalytic properties enable the efficient conversion of reactants to desired products, improving the overall efficiency and yield of these processes.
Used in Emulsion Hardening:
Chromic acetate is also utilized as an emulsion hardener, particularly in the production of water-based emulsions. It helps in the formation of a stable and durable emulsion by cross-linking the emulsion components, resulting in improved emulsion stability and performance.
Air & Water Reactions
Water soluble.
Reactivity Profile
Chromic acetate gives aqueous solutions that are basic (neutralize acids). These neutralizations generate only a little heat. Neither a strong reducing agent nor oxidizing agent, but can serve as both.
Hazard
Toxic by ingestion.
Health Hazard
INHALATION: Irritating. It can produce ulcerations in the respiratory system, perforation of the nasal septum, pneumonitis and bronchial carcinoma. EYES: Irritation. SKIN: May cause dermatitis to exposed skin. Can produce ulcerations and sensitizing reactions.
Flammability and Explosibility
Nonflammable
Safety Profile
Questionable
carcinogen with experimental tumorigenic
data. Moderately toxic by intravenous route.
Human mutation data reported. See also

Check Digit Verification of cas no
The CAS Registry Mumber 1066-30-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,0,6 and 6 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1066-30:
(6*1)+(5*0)+(4*6)+(3*6)+(2*3)+(1*0)=54
54 % 10 = 4
So 1066-30-4 is a valid CAS Registry Number.

Paragraph 0016; 0021; 0025; 0029; 0033, (2016/10/10)
The invention relates to a preparation method of acid black 172. The method comprises the following steps: (1) diazotizing 6-nitro-1-diazo-2-naphthol-4-sulfonic acid by using zinc chloride as a catalyst to obtain a diazo solution; (2) directly adding 2-naphthol into the diazo solution, regulating the pH value with sodium hydroxide, and carrying out coupling to obtain a coupling solution; (3) carrying out chromization on chromic sulfate and acetic acid to obtain a chromizing solution; and (4) adding the chromizing solution into the coupling solution, carrying out complexation, adding salicylic acid to remove chromium to obtain an acid black 172 slurry, and directly carrying out spray drying to obtain the acid black 172 dry powder. The method has the advantages of simple production technique, high production efficiency and fewer side reactions and impurities. The product has the advantages of high quality and no heavy metal chromium, and can be directly subjected to spray drying without salting-out, so the production cost is low.
Catalyzed process for producing metal carboxylates for use as animal feed supplements
-
, (2008/06/13)
A catalyzed process is disclosed for producing a polyvalent metal C2 -C3 carboxylate having the formula M(CH3 (CH2)x COO--)y, wherein M is the polyvalent metal cation that is manganese (Mn+2), cobalt (Co+2), or chromium (Cr+3), x is zero or 1 and y is an integer equal to the cationic charge of M. The polyvalent metal C2 -C3 carboxylate is prepared by admixing (i) a dry polyvalent metal compound that is an oxide, hydroxide or carbonate of Mn+2, Co+3 or Cr+3, (ii) an anhydrous C2 -C3 carboxylic acid, and (iii) a catalytic agent at a relative molar ratio of about 1:2-10:0.01-3 in the absence of an added solvent or other diluent to form a reaction mixture. The reaction mixture is heated to complete the reaction, remove the produced water and about 80 percent of the unreacted carboxylic acid. The product in residual carboxylic acid is solidified, ground and the product is recovered. The metal carboxylates can be used as biologically available and economical sources of trace metal ions for supplementation in animal diets.
