78-51-3 Usage
Chemical Properties
Slightly yellow, oily liquid. Insoluble or limited solubility in glycerol,
glycols, and certain amines; soluble in most
organic liquids. Combustible.
Uses
Different sources of media describe the Uses of 78-51-3 differently. You can refer to the following data:
1. Tris(2-butoxyethyl) phosphate may be used as an analytical reference standard for the quantification of the analyte in herring gull eggs, house dust, and urine samples using liquid chromatography technique.
2. Primary plasticizer for most resins and elastomers,
floor finishes and waxes, flame-retarding
agent.
Definition
ChEBI: A trialkyl phosphate in which the alkyl group specified is 2-butoxyethyl.
General Description
Tris(2-butoxyethyl) phosphate is an organic flame retardant. It shows PXR agonistic activity. Tris(2-butoxyethyl) phosphate was detected and quantified during the analysis of herring gull eggs by liquid chromatography-electrospray ionization(+)-tandem mass spectrometry.
Air & Water Reactions
Water soluble.
Reactivity Profile
Organophosphates, such as Tris(2-butoxyethyl) phosphate, are susceptible to formation of highly toxic and flammable phosphine gas in the presence of strong reducing agents such as hydrides. Partial oxidation by oxidizing agents may result in the release of toxic phosphorus oxides. Tris(2-butoxyethyl) phosphate may react with oxidizers. .
Fire Hazard
Tris(2-butoxyethyl) phosphate is combustible.
Flammability and Explosibility
Nonflammable
Safety Profile
A poison by
intravenous route. Moderately toxic by
ingestion. A skin and eye irritant.
Combustible when exposed to heat or
flame. Dangerous; see also PHOSPHATES;
can react with oxidizing materials. To fight
fire, use water, foam, CO2, dry chemical.
When heated to decomposition it emits
toxic fumes of POx.
Check Digit Verification of cas no
The CAS Registry Mumber 78-51-3 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 7 and 8 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 78-51:
(4*7)+(3*8)+(2*5)+(1*1)=63
63 % 10 = 3
So 78-51-3 is a valid CAS Registry Number.

Paragraph 0047-0087, (2019/11/04)
The invention relates to a high-purity (butoxy ethyl) phosphate ester of preparation method, the method comprises the following steps: 1) the vacuum condition through the phosphorus oxychloride and ethylene glycol monobutyl ether in the Lewis catalyst under the action of reaction; 2) after the reaction, vacuum-recycle a large amount of glycol flatting, reactant in ethylene glycol monobutyl ether content in the range of 5 - 10%, stop distilling; 3) alkali to neutralize, in and to PH=5 - 8, then distilled under reduced pressure, until the ethylene glycol monobutyl ether content is less than 0.1% stop distilling, to obtain crude; 4) washing the crude product is separated, washed in addition to the water of the product is distilled under reduced pressure to obtain high-purity (butoxy ethyl) phosphate ester. The method of the invention is simple, the purity of the product, in color, to improve the yield is very large. (by machine translation)
