Technical Field
The invention relates to the field of antibiosis/sterilization, in particular to an organosilicon quaternary ammonium salt, a preparation method and application thereof.
Background
At present, there are many kinds of sterilization chemicals which are applied in China, and each has various advantages and characteristics. The organosilicon quaternary ammonium salt is used as a high-efficiency, safe, nontoxic and harmless functional antibacterial finishing agent, and is widely applied to the industries of medicine, textile, cosmetics and the like. The organic silicon quaternary ammonium salt fabric finishing agent is particularly suitable for antibacterial finishing and general finishing of fabrics, and the fabrics finished by the organic silicon quaternary ammonium salt not only have excellent antibacterial performance, but also have good antistatic performance, and simultaneously have water absorption and sweat absorption properties, smooth softness, rebound resilience and the like. It is also especially suitable for the antibacterial disinfection in public places such as hospitals, kindergartens, schools and markets; and is particularly suitable for water treatment and other aspects of antibacterial/bactericidal treatment.
The organosilicon quaternary ammonium salt is generally prepared by reacting C12-C22 alkyl tertiary amine with halogenated propyl alkoxy silane in a solvent under the action of a catalyst. In the production process of the alkyl tertiary amine, a fatty acid cyanidation reaction and a hydrogenation process are required, so that the alkyl tertiary amine is not easy to obtain and has high safety requirement. Moreover, because the hydrophobic property of the long-chain alkyl is very strong, the water solubility of the product is poor, the product is not suitable for high-concentration use, and solvents such as methanol, ethanol and the like are required to be used simultaneously.
Disclosure of Invention
Therefore, the technical problem to be solved by the invention is to overcome the defect of poor water solubility of the organosilicon quaternary ammonium salt in the prior art, thereby providing the organosilicon quaternary ammonium salt.
The invention also provides a preparation method of the organic silicon quaternary ammonium salt, aiming at overcoming the defects of difficult obtainment and high safety requirement in the preparation process of the organic silicon quaternary ammonium salt in the prior art.
In order to solve the problems, the invention provides a quaternary ammonium salt of organosilicon, which has the following structural formula:
[R1-CO-NH-CH2-CH2-CH2-N（CH3）2-CH2-CH2-CH2-Si（OR2）3]X，
wherein R is1Is a C12-C22 fatty alkyl radical, R2Is methyl or ethyl, and X is Cl ion, Br ion or I ion.
Preferably, R1 is an unsaturated fatty alkyl group of C12-C22, preferably a palmityl group; or R1 is a saturated fatty alkyl group of C12-C22, preferably lauryl.
The invention also provides a method for preparing the organosilicon quaternary ammonium salt, which comprises the following steps: and (3) carrying out synthetic reaction on fatty acid amide, halogenated propyl alkoxy silane and a reaction solvent to obtain the organosilicon quaternary ammonium salt.
Preferably, the molar ratio of fatty acid amide to halopropyl alkoxysilane is 1:0.8 to 1.2.
As a preferable scheme, the reaction temperature of the synthesis reaction is 50-150 ℃, preferably 60-120 ℃; the reaction time of the synthesis reaction is 20 to 200 hours, preferably 30 to 120 hours.
Preferably, the reaction solvent is any one of methanol, ethanol, propanol, isopropanol, and ethylene glycol, or a mixture thereof.
Preferably, the fatty acid amide is formed by condensation reaction of C12-C22 fatty acid and dimethyl propylene diamine.
Preferably, the molar ratio of the fatty acid of C12-C22 to the dimethyl propylene diamine is 1:0.8-1.2, and the reaction temperature of the condensation reaction is 120-240 ℃.
Preferably, the fatty acid of C12-C22 is coconut oil acid or lauric acid, and the halogenated propyl alkoxy silane is halopropyl trimethoxy silane or halopropyl triethoxy silane.
The invention also discloses application of the organic silicon quaternary ammonium salt in textile finishing, antibiosis/sterilization in public places or water treatment.
The technical scheme of the invention has the following advantages:
1. compared with the organic silicon quaternary ammonium salt in the market, the organic silicon quaternary ammonium salt provided by the invention has better degradability, is more environment-friendly due to the introduction of amido bond, has better water solubility, and has equivalent or better antibacterial/bactericidal capability.
2. According to the invention, fatty acid amide (namely fatty acid PKO) is generated by adopting the condensation reaction of C12-C22 fatty acid and dimethyl propane diamine, and then the fatty acid PKO and halogenated propyl alkoxy silane are used for synthesizing the organic silicon quaternary ammonium salt, so that the raw materials are easy to obtain, the reaction is mild, three wastes are not discharged, and a dangerous chemical process is not required.
3. The diluted solution of the organosilicon quaternary ammonium salt is used for antibacterial finishing of fabrics and antibacterial/sterilization of public places such as hospitals, kindergartens, schools, markets and the like; it may also be used in other sterilization settings including, but not limited to, water treatment, etc. And because of the introduction of amide chemical bonds, the product is bonded with a protected object such as fabric and the like more firmly. In addition, the molecular structure introduces amido bond with the same atomic group structure as peptide bond in protein and the structure has better water solubility, thereby having better effect of killing virus.

Of course, in other embodiments, the reaction solvent may also be removed after the synthesis reaction.
Preferably, the molar ratio of the fatty acid amide to the halogenated propyl alkoxysilane is 1 (0.8-1.2); the reaction temperature of the synthesis reaction is 50-150 ℃, preferably 60-120 ℃; the reaction time of the synthesis reaction is 20 to 200 hours, preferably 30 to 120 hours. Wherein the reaction solvent is any one or a mixture of methanol, ethanol, propanol isopropanol and ethylene glycol.
In a preferred embodiment, the fatty acid amide is formed by the condensation reaction of C12-C22 fatty acid and dimethyl propylene diamine. The molar ratio of the fatty acid of C12-C22 to the dimethyl propane diamine is 1 (0.8-1.2), and the reaction temperature of the condensation reaction is 120-240 ℃. The fatty acid of C12-C22 is coconut oil acid or lauric acid, and the halogenated propyl alkoxy silane is halogen propyl trimethoxy silane or halogen propyl triethoxy silane.
According to the invention, fatty acid amide (namely fatty acid PKO) is generated by adopting the condensation reaction of C12-C22 fatty acid and dimethyl propane diamine, and then the fatty acid PKO and halogenated propyl alkoxy silane are used for synthesizing the organic silicon quaternary ammonium salt, so that the raw materials are easy to obtain, the reaction is mild, three wastes are not discharged, and a dangerous chemical process is not required.
The embodiment of the invention also discloses application of the organic silicon quaternary ammonium salt in textile finishing, antibiosis/sterilization in public places or water treatment. The diluted solution of the organosilicon quaternary ammonium salt is used for antibacterial finishing of fabrics and antibacterial/sterilization of public places such as hospitals, kindergartens, schools, markets and the like; it may also be used in other antimicrobial/germicidal locations including, but not limited to, water treatment, etc. And because of the introduction of amide chemical bonds, the product is bonded with a protected object such as fabric and the like more firmly. In addition, the amido bond with the same atomic group structure as the peptide bond in the protein and the better water solubility of the structure are introduced into the molecular structure, so the structure has better effect of killing the virus.
