141-75-3 Usage

Chemical Properties

Butyryl chloride is a colorless to light yellow liquid with a strong pungent odor. It undergoes vigorous hydrolysis with water; decomposes in water; soluble in almost aprotic organic solvents. It is used as an intermediate for organic synthesis for the preparation of pharmaceuticals, agrochemicals, dyes, cellulose esters, and peroxide compounds.

Uses

Different sources of media describe the Uses of 141-75-3 differently. You can refer to the following data:
1. Butyryl chloride is used as an intermediate for the synthesis of active pharmaceutical ingredients benzoyl peroxide, t-butyl perbenzoate, and benzophenone. It is also used as an acylation reagent. Further, it is used in the preparation of peroxides such as benzoyl peroxide, benzophenone and t-butyl perbenzoate. In addition to this, it is involved in the preparation of chromones and antiproliferative agents. Butyryl chloride has been used to esterify wood meal dissolved in the ionic liquid, 1-butyl-3-methylimidazolium chloride.
2. Butyryl chloride has been used to esterify wood meal dissolved in the ionic liquid, 1-butyl-3-methylimidazolium chloride.

General Description

A clear colorless liquid with a sharp odor. Slightly denser than water. Flash point near 20°F. Severely irritates skin, eyes, and mucous membranes. Used to make other chemicals.

Air & Water Reactions

Highly flammable. Fumes in air. Decomposes exothermically in water to give corrosive hydrochloric acid.

Reactivity Profile

Butyryl chloride slowly dissolves in water with decomposition and formation of a weakly acidic solution. May react vigorously or explosively if mixed with diisopropyl ether or other ethers in the presence of trace amounts of metal salts [J. Haz. Mat., 1981, 4, 291].

Health Hazard

Extremely destructive to the mucous membranes, upper respiratory tract, eyes, and skin. Inhalation may cause death as a result of spasm, inflammation and edema of the larynx and bronchi, chemical pneumonitis, and pulmonary edema. Symptoms of exposure include burning sensation, coughing, wheezing, laryngitis, shortness of breath, headache, nausea, and vomiting.

Fire Hazard

Special Hazards of Combustion Products: Emits toxic fumes of chlorine gas

Flammability and Explosibility

Flammable

Purification Methods

Check IR to see if there is a significant peak at 3000-3500 cm-1 (br) for OH. If OH is present then reflux with less than one mole equivalent of SOCl2 for 1hour and distil directly. The fraction boiling between 85-100o is then refractionated at atmospheric pressure. Keep all apparatus free from moisture and store the product in sealed glass ampoules under N2. LACHRYMATORY; handle in a good fume hood. [Hefferich & Schaeffer Org Synth Coll Vol I 147 1941, Beilstein 2 IV 803.]

Check Digit Verification of cas no

The CAS Registry Mumber 141-75-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,4 and 1 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 141-75:
(5*1)+(4*4)+(3*1)+(2*7)+(1*5)=43
43 % 10 = 3
So 141-75-3 is a valid CAS Registry Number.

A conformational study of Butyryl chloride (cas 141-75-3) using chirped pulse Fourier transform microwave spectroscopy and quantum chemical calculations09/29/2019

The pure rotational spectrum of butyryl chloride has been recorded between 8 and 16GHz using a chirped pulse, Fourier transform microwave spectrometer. The transitions recorded were assigned to two different conformers which have previously been designated syn-gauche and syn-anti. Quantum chemic...detailed
