9005-53-2 Usage
Description
LIGNINE is an abundant phenylpropane polymer found in all vascular plants, acting as the "glue" for cellulose and hemicellulose constituents of plants. It provides the hardness and rigidity of tree trunks and the stems of perennial plants, and is an important skeletal component of secondary cell walls.
Used in Chemical Industry:
LIGNINE is used as a precursor for the synthesis of various products such as vanillin, syringic aldehyde, and dimethyl sulfoxide.
Used in Plastics Industry:
LIGNINE is used as an extender for phenolic plastics to improve their properties and reduce costs.
Used in Rubber Industry:
LIGNINE is used to strengthen rubber, especially for shoe soles, enhancing the durability and performance of rubber products.
Used in Oil and Gas Industry:
LIGNINE is used as an oil mud additive in drilling operations, improving the performance and stability of drilling fluids.
Used in Construction Industry:
LIGNINE is used as an asphalt emulsion stabilizer, helping to create more stable and durable asphalt mixtures for road construction and pavements.
Used in Agricultural Industry:
LIGNINE is used as a protein precipitant, aiding in the separation and purification of proteins in various agricultural processes.
Check Digit Verification of cas no
The CAS Registry Mumber 9005-53-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 9,0,0 and 5 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 9005-53:
(6*9)+(5*0)+(4*0)+(3*5)+(2*5)+(1*3)=82
82 % 10 = 2
So 9005-53-2 is a valid CAS Registry Number.

Photocatalytic degradation of lignin and lignin models, using titanium dioxide: The role of the hydroxyl radical

The role of hydroxyl radicals on the degradation of lignins during a cellulosic pulp bleaching process including a photocatalytic stage, was assessed using peroxyformic acid lignins EL1 and REL1 and two phenolic biphenyl lignin models 1 and 2. The irradiations were performed in the absence of photocatalyst TiO2 and H2O2 (condition a), in the presence of TiO2 (condition b) and in the presence of H2O2 (condition c). The experiments were conducted in alkaline (pH? 11) aqueous ethanol solutions with oxygen bubbling. The relative phenolic content of the irradiated solutions, which is indicative of the involvement of hydroxyl radicals, was determined by ionization absorption spectroscopy. The results obtained show that the catalyzed reaction involves both degradation of the phenolate groups by electron transfer and hydroxylation of the lignin aromatic structure. Benzyl alcohol structural elements in sodium borohydride reduced lignin REL1 and compound 2 were also found as good trapping agents for the hydroxyl radicals. The degradation of EL1 was studied by measuring its fluorescence emission by comparison to the fluorescence of compound 2. The emission spectra indicate that some biphenyl phenolate anions in EL1 are reacting under UV/visible irradiation and some others, probably polyphenolic chromophores emitting less fluorescence, are formed.
