Used in Plastics Industry:
In the plastics industry, PEG-8 LAURATE is used as a viscosity modifier. It helps to control the flow and consistency of the plastic materials, ensuring a smooth and even application during manufacturing processes.
Used in Textile Chemicals Industry:
PEG-8 LAURATE is used as an emulsifier and lubricant in textile chemicals. It aids in the even distribution of dyes and other chemicals on fabrics, as well as providing a smooth and even finish to the textile materials.
Used in Coatings Industry:
In the coatings industry, PEG-8 LAURATE is used as an emulsifier and pigment dispersant. It helps to create stable dispersions of pigments in coatings, ensuring a uniform color distribution and improving the overall quality of the final product.
Check Digit Verification of cas no
The CAS Registry Mumber 35179-86-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,5,1,7 and 9 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 35179-86:
(7*3)+(6*5)+(5*1)+(4*7)+(3*9)+(2*8)+(1*6)=133
133 % 10 = 3
So 35179-86-3 is a valid CAS Registry Number.

Combinatorial synthesis of PEG oligomer libraries

Page/Page column 11, (2010/02/15)
A simple chain-extending approach was established for the scale-up of the monoprotected monodisperse PEG diol materials. Reactions of THP-(OCH2CH2)n—OMs (n=4, 8, 12) with a large excess of commercially available H—(OCH2CH2)n—OH (n=1-4) under basic conditions led to THP-(OCH2CH2)n—OH (n=5-15). Similarly, Me-(OCH2CH2)n—OH (n=4-11, 13) were prepared from Me-(OCH2CH2)n—OMs (n=3, 7, 11). For the chain elongation steps, 40-80% yields were achieved through extraction purification. PEG oligomer libraries I and II were generated in 50-95% overall yields by alkylation or acylation of THP-(OCH2CH2)n—OH (n=1-15) followed by deprotection. Alkylation of Me-(OCH2CH2)n—OH (n=1-11, 13) with X—(CH2)m—CO2R (X=Br or OMs) and subsequent hydrolysis led to PEG oligomer library III in 30-60% overall yields. Combinatorial purification techniques were adapted to the larger-scale library synthesis. A total of 498 compounds, each with a weight of 2-5 g and a minimum purity of 90%, were synthesized.
