2179-59-1 Usage
Chemical Properties
Different sources of media describe the Chemical Properties of 2179-59-1 differently. You can refer to the following data:
1. Allyl propyl disulfi de is a pale yellow liquid with a pungent odor and is insoluble in water.
It decomposes on burning, producing sulfur oxides, and it also gives off irritating or toxic fumes (or gases) in a fi re. It reacts with oxidants. Allyl propyl sulfi de is used as a synthetic
fl avor and food additive. Allyl propyl disulfi de is the chief volatile component of onion oil
as well as being a volatile component of chives and garlic.
2. Onion oil is obtained by steam distillation of the crushed bulbs of the
common onion, Allium cepa L. It is produced mainly in Mexico, China,and Egypt, and, in smaller quantities, also in Europe (France, Hungary)
and is an amber-yellow to amber liquid with a strongly pungent, lasting,
characteristic onion odor.d2525 1.050–1.135; n20D 1.5495–1.5695
3. Colorless to yellowish liquid; fruity, garlic aroma.
Occurrence
Reported as the chief volatile constituent in onion oil and found in raw cabbage, chive, garlic oil, leek and
onion.
Aroma threshold values
High strength odor, sulfurous type; recommend smelling in a 0.10% solution or less.
Taste threshold values
Taste like that of cooked onions.
General Description
Clear pale yellow liquid with a pungent odor.
Air & Water Reactions
Insoluble in water.
Reactivity Profile
Allyl Propyl Disulfide may react vigorously with strong oxidizing agents. Incompatible with acids, diazo and azo compounds, halocarbons, isocyanates, aldehydes, alkali metals, nitrides, hydrides and other strong reducing agents. Reactions with these materials generate heat and in many cases hydrogen gas. May liberate hydrogen sulfide upon decomposition or reaction with an acid.
Health Hazard
Exposures to allyl propyl disulfi de are absorbed into the body by inhalation and by ingestion.
It causes a burning sensation, cough, chest tightness, nausea, vomiting, irritation to
the eyes, skin, and respiratory tract. Based on animal and human experimental data, allyl
propyl sulfi de is regarded as an occupational skin sensitizer.
Fire Hazard
Allyl Propyl Disulfide is combustible.
Contact allergens
With allicin and diallyl sulfide, allylpropyldisulfide is
one of the allergens in garlic (Allium sativum L.). See
also Chap. 46.
Safety Profile
Skin irritant. When heated to decomposition it emits acrid smoke and irritating fumes
storage
Allyl propyl disulfi de should be separated from oxidants.
Precautions
During use/handling of allyl propyl disulfi de, occupational workers should use safety
goggles or eye protection in combination with breathing protection and protective gloves.
Many of the chemical reactions may result in a hazardous situation, i.e., generation of
flammable or toxic chemicals, fi re or detonation.
Check Digit Verification of cas no
The CAS Registry Mumber 2179-59-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,1,7 and 9 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 2179-59:
(6*2)+(5*1)+(4*7)+(3*9)+(2*5)+(1*9)=91
91 % 10 = 1
So 2179-59-1 is a valid CAS Registry Number.

Crack healing and reclaiming of vulcanized rubber by triggering the rearrangement of inherent sulfur crosslinked networks
Xiang,Qian,Lu,Rong,Zhang
supporting information, p. 4315 - 4325 (2015/08/11)
CuCl2 has been shown to effectively catalyze reshuffling of the inherent sulfur crosslinked networks of vulcanized rubber. Once activated, CuCl2-based complex catalysis enables disulfide metathesis through circulated crossover reactions among disulfide and polysulfide bonds without forming radicals and ionic intermediates. By taking advantage of this mechanism, the model material of this study, vulcanized polybutadiene rubber, acquires thermal remendability as characterized by repeated restoration of mechanical properties. Moreover, it can be reprocessed like thermoplastics. The compositions and fabrication of the model material simulate those of industrial vulcanized rubber, so as to facilitate formulation optimization under the circumstances close to the actual situation for possible future practical applications. It is hoped that the results of the present preliminary exploration would provide the basis for extending the service life and developing new recycling techniques of vulcanized rubber, which is produced, used and scrapped in large quantities every day.
