110-40-7 Usage

Description

Dibutyl sebacate (DBS) is an organic colorless liquid chemical, a dibutyl ester of sebacic acid.Its main use is as a plasticizer in production of plastics, namely cellulose acetate butyrate, cellulose acetate propionate, ethyl cellulose, polyvinyl butyral, polyvinyl chloride, polystyrene, and many synthetic rubbers (especially nitrile rubber and neoprene) and other plastics. It can be used for plastics in use in the food packaging industry, in plastics used for medical devices, and for pharmaceutical applications, e.g. as a plasticizer for film coating of tablets, beads, and granules.[2] It is also used as a lubricant in shaving lotions, and a flavoring additive in non-alcoholic beverages, ice cream, ices, candy, and baked goods. It provides excellent compatibility with a range of plastic materials, superior properties at low temperatures, and good oil resistivity. Its other names include Morflex, Kodaflex, polycizer, Proviplast 1944 and PX 404. Dibutyl sebacate is also used as a desensitizer in Otto fuel II, a torpedo monopropellant.

Application

Dibutyl Sebacate (DBS) provides superior low temperature flexibility properties to a variety of polymers. The low temperature benefits of DBS make it an excellent choice for vinyl food contact films used in refrigeration. It provides excellent compatibility with a range of plastic materials including vinyls, acrylics, nitrile rubber, Buna-n rubber and some cellulosics.

Content analysis

It can be determinated by a non-polar column method in GT-10-4 or by the method I in the ester assay (OT-18). The amount of sample taken was 1 g. The equivalent factor (e) in the calculation is 64.59.

Toxicity

LD50 14470 mg/kg (rat, oral).

Maximum level

FEMA (mg/kg): soft drinks 4.1; cold drinks 9.1; candy 21; baked goods 41; pudding class 3.2 to 19.

Uses

Different sources of media describe the Uses of 110-40-7 differently. You can refer to the following data:
1. A permitted flavoring listed in GB 2760-96. Mainly used in the preparation of grapes, pears and other flavors and fruit flavor solvent. In addition, it is often used as plasticizer for resin and vinyl resin as its better compatibility with nitrocellulose and butyl acetate cellulose. It can also be used as synthesis solvent for organic synthesis, solvents and pigments, pharmaceutical intermediates and polymers compound.
2. Diethyl Sebacate is a flavoring agent that is a liquid, colorless to pale yellow in appearance with a slight odor. it is insoluble in water and miscible in alcohol, ether, and other organic solvents. it is obtained by chemical synthesis. it is also termed ethyl sebacate.

Production method

It is derived by esterification of succinic anhydride and ethanol; It can also be obtained through heating esterification of sebacic acid and ethanol in the presence of concentrated sulfuric acid.

Check Digit Verification of cas no

The CAS Registry Mumber 110-40-7 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,1 and 0 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 110-40:
(5*1)+(4*1)+(3*0)+(2*4)+(1*0)=17
17 % 10 = 7
So 110-40-7 is a valid CAS Registry Number.

The synthesis of di-carboxylate esters using continuous flow vortex fluidics

Britton, Joshua,Dalziel, Stuart B.,Raston, Colin L.

, p. 2193 - 2200 (2016/04/19)

A vortex fluidic device (VFD) is effective in mediating the synthesis of di-esters at room temperature. Processing under ambient conditions allows for a simple and efficient synthesis, whilst operating under continuous flow addresses scalability. The rotational speed of the sample tube and the flow rate were critical variables during reaction optimization, and this relates to the behaviour of the fluid flow at a molecular level. Whilst at specific rotational speeds the tube imparts a vibrational response into the fluid flow, the flow rate dictates residence time and the ability to maintain high levels of shear stress. The combination of mechanically induced vibrations, rapid micromixing, high levels of shear stress and water evaporation results in yields up to 90% for 3.25 minutes or less residence time. These results are key for devising greener and more efficient processes both mediated by the VFD and other continuous flow platforms.

Synthesis of fluorescent carboxylic acid ligands for construction of monolayers on nanostructures

Jadhav, Sushilkumar A.

, p. 1640 - 1646,7 (2020/09/09)

Two new long-chain carboxylic acids (1, 2) bearing strong fluorescent group pyrene as ligands for Self-Assembled Monolayers (SAMs) have been synthesized. The multistep targeted synthesis is accomplished by use of Pyren-1-yl methylamine hydrochloride and employing simplified synthetic protocols. Compound 2 contains a chiral center purposely introduced along the atom chain in order to make it suitable for chiro-optical studies of the resulting SAMs.
