126-86-3 Usage
Chemical Properties
2,4,7,9-Tetramethyl-5-decyne-4,7-diol is white to pale yellow low melting mass
Uses
Different sources of media describe the Uses of 126-86-3 differently. You can refer to the following data:
1. 2,4,7,9-Tetramethyl-5-decyne-4,7-diol is an acetylene glycol derivative used in water-based coatings and has both antifoaming and surfactant properties. It is highly toxic and have been found in acrylic adhesives used for food packaging multilayers manufacturing.
2. 2, 4, 7, 9-tetramethyldec-5-yne-4,7-diol may be used to dope poly[9,9-bis(6′-(diethanolamino)hexyl)-fluorene],that acts as an interfacial layer in a heterojunction solar cell.
General Description
2, 4, 7, 9-tetramethyldec-5-yne-4,7-diol is a well-known acrylic adhesive. It has amphiphilic characteristics. It is used a dopant in a heterojunction solar cell, it assists in the formation of a homogeneous interfacial layer over the photoactive layer. Doping results in decreasing the absorption of photons in the underneath photoactive layer, thereby in enhancing the photocurrent density.
Flammability and Explosibility
Nonflammable
Check Digit Verification of cas no
The CAS Registry Mumber 126-86-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,2 and 6 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 126-86:
(5*1)+(4*2)+(3*6)+(2*8)+(1*6)=53
53 % 10 = 3
So 126-86-3 is a valid CAS Registry Number.

Method for the combined production of tetramethyldecyndiol and dimethylhexynyl alcohol
-
Paragraph 0025-0040, (2022/01/12)
A method for co-producing tetramethyldecyndiol and dimethylhexynyl alcohol, using 4-methyl-2-pentanone and acetylene as raw material, potassium hydroxide as a catalyst, and organic solvent as a dispersant, first reacting 4-methyl-2-pentanone with acetylene at atmospheric pressure or low pressure at a lower temperature to form a dimethylhexynyl alcohol-potassium hydroxide complex, and then mixing it with 4-methyl-2-pentanone quickly reacts through a high-temperature reaction tube to generate tetramethyldyne glycol. After the reaction product is water-relieved of potassium hydroxide, each target product is collected by fractionation. The present invention has the characteristics of short reaction time, low catalyst consumption and easy recovery of products.
