Butyl disulfide(CAS#629-45-8)

Introduction

N-butyl disulfide is an organosulfur compound. The following is an introduction to the properties, uses, preparation methods and safety information of n-butyl disulfide:- N-butyl disulfide is a colorless to light yellow liquid with a pungent odor. - It is soluble in organic solvents such as alcohols, ethers, and hydrocarbons, but almost insoluble in water. - N-butyl disulfide has a low ignition point, is flammable in the air, and can produce toxic sulfide gases. Uses:- N-butyl disulfide is mainly used as a vulcanization reagent in organic synthesis. - In chemical reactions, it can react with alkyl halides to form sulfides, which are used to synthesize compounds such as thioethers and thioesters. Preparation method:- N-butyl disulfide can be prepared by the reaction of n-butyl bromide and sodium sulfide in organic solvents. The reaction equation is as follows:2(CH3CH2CH2CH2Br) + Na2S → (CH3CH2CH2CH2)2S + 2NaBrSafety Information:- N-butyl disulfide is an irritant substance that can cause irritation and inflammation in contact with the skin and eyes. - It is volatile and needs to be used in a well-ventilated laboratory environment. - Personal protective equipment such as protective gloves, goggles, and lab coats are required during handling. - Avoid contact with fire sources and smoke inhalation. In case of inhalation, the victim should be moved immediately to a place with fresh air and medical attention should be sought as soon as possible. Please follow the safety operating procedures and refer to the detailed safety information provided by the supplier during use.

Application
Dibutyl disulfide (DBDS) is a versatile organosulfur compound valued for its unique reactivity and sensory properties. As a chemical intermediate, it is utilized in organic synthesis for the preparation of other sulfur-containing molecules and as a raw material in specialty chemical production. In the petroleum refining industry, it serves as an effective sulfurizing agent for catalyst pre-sulfiding, where it releases active sulfur under high-temperature conditions to protect hydrogenation catalysts and extend their lifespan. In the rubber and lubrication industry, it functions as a vulcanizing additive for rubber processing and lubricant formulations. In the flavor and fragrance sector, dibutyl disulfide exhibits a distinctive sulfurous odor that, upon extreme dilution, imparts characteristic violet and rose notes, making it valuable in floral and fruit-flavored products. Additionally, it is used in food preservation as a candidate preservative, protecting against pathogens.
