13674-87-8 Usage
Chemical Properties
Tris(1,3-dichloro-2-propyl)phosphate is a clear colorless viscous liquid with a relatively low molecular weight, low water solubility, and low lipophilicity (as indicated by log Kow).
Uses
Different sources of media describe the Uses of 13674-87-8 differently. You can refer to the following data:
1. Tris(1,3-dichloro-2-propyl) Phosphate is a flame retardant present in polyurethane foams.
2. Tris(1,3-dichloro-2-propyl)phosphate [TDCPP] is a halogenated phosphorus flame retardant used in a variety of sectors, including manufacturing of paints/coatings, furniture and related products, building/construction materials, fabrics/textiles/leather products, and foam seating and bedding products (EPA, 2012).
It is used extensively as an additive to flexible polyurethane foams (PUFs). Its end uses include molded automotive seating foam (e.g., seat cushions and headrests), slabstock foam in furniture, automotive fabric lining, and car roofing (ECHA, 2013). It is a high production volume chemical.
General Description
Clear colorless viscous liquid. Generally a super-cooled liquid at room temperature but may occasionally solidify when held at low temperatures for prolonged periods.
Air & Water Reactions
Insoluble in water.
Reactivity Profile
Fyrol FR 2 hydrolyzes slowly when refluxed with an aqueous acid. Under alkaline conditions, Fyrol FR 2 exhibits a slow cleavage. Fyrol FR 2 has plasticizing properties and, as such, may soften or deteriorate certain plastics and elastomers (particularly vinyl-based resin, neoprene and natural rubbers).
Fire Hazard
Fyrol FR 2 is combustible.
Safety Profile
Moderately toxic by
ingestion. An experimental teratogen. Experimental reproductive effects.
Questionable carcinogen with experimental
carcinogenic data. Mutation data reported.
When heated to decomposition it emits
toxic fumes of Cland POx.
Environmental Fate
A series of studies have been performed to evaluate the environmental fate and bioaccumulation potential of Tris(1,3-dichloro-2-propyl)phosphate (TDCPP).EU concluded that TDCPP is expected to be persistent in water, sediment, sewage sludge, and soil. When emitted to the environment, the EU concluded that TDCPP will likely adsorb to particulate matter, based on its low volatility and relatively high adsorption coefficient. The Henry’s law constant suggests that TDCPP will preferentially partition to water, rather than air. When assessing TDCPP's potential for persistence or bioaccumulation, the EU determined that TDCPP can potentially be persistent or very persistent and that it does not meet the criteria for bioaccumulative or very bioaccumulative compounds.
Check Digit Verification of cas no
The CAS Registry Mumber 13674-87-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,6,7 and 4 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 13674-87:
(7*1)+(6*3)+(5*6)+(4*7)+(3*4)+(2*8)+(1*7)=118
118 % 10 = 8
So 13674-87-8 is a valid CAS Registry Number.

Paragraph 0014-0018, (2019/04/09)
The invention discloses a method for preparing tris(1,3-dichloropropyl) phosphate. The method specifically comprises the following steps: adding phosphorus oxychloride and 1,3-dichloropropanol into areaction kettle at a time, stirring the phosphorus oxychloride and the 1,3-dichloropropanol, raising the temperature to 110 DEG, performing a reaction on the phosphorus oxychloride and the 1,3-dichloropropanol for 1-3h, raising the temperature to 180 DEG according to the 15-30-DEG C gradient, removing generated hydrogen chloride gas under a negative pressure condition and reducing the temperature,so as to obtain a crude product; washing the crude product with alkali and water in sequence and distilling, so as to obtain the tris(1,3-dichloropropyl) phosphate. Under a catalyst-free condition, the method has the advantages of being high in product purity, high in conversion rate, mild in process conditions, and simple in operation, avoiding a problem of aftertreatment of a catalyst and lowering the production cost.
