Description
Technical field
The present invention relates to leather agent preparation technical field more particularly to a kind of leather high-effective cationic surfactants
Preparation method.
Background technique
In recent years, leather and fur products kind and yield are continuously increased, and class is also continuous with the rapid development of leather industry
It submits, the requirement to various surfactants is also higher and higher, and surfactant can send other chemical industry in technical process
The comprehensive and application effect of material reduces emissions, improves the appearance and inherent quality of leather and fur products.
It is seen in synthesis, effect of the surfactant played in leather making process mainly has antisepsis and sterilization, water proof anti-soil, improvement
Gloss or feel etc. also have the function of dispersion infiltration etc.；Use anti-ionic surfactant at present, these activating agents are main more
There are multivalent metal salt, nitrogenous compound with depth and tint retention, main ingredient is increased, these substances are easy to consumer health
It has an impact, can also influence ecological environment to some extent.
Summary of the invention
The purpose of the present invention is to provide a kind of preparation method of efficient leather cationic surfactant, the present invention
Obtained cationic surface active agent be fully extended for that in leather, can make to remove from office base, make leather and fur products with more softness
Property.
In order to solve the above technical problems, the present invention provides a kind of preparation side of leather high-effective cationic surfactant
Method, comprising the following steps:
(1) certain lauryl amine is added into three-necked flask, is slow added into formic acid solution, stirs, is slowly heated, heating
To after 85 DEG C, then formalin is slowly added dropwise, reacts 8 hours；
(2) to fully reacting, liquid is poured into beaker, aqueous slkali is added into beaker, adjust its pH value be 10-12 it
Between；
(3) it after static a period of time, takes upper layer oily liquids to be evaporated under reduced pressure, obtains colourless transparent liquid；
(4) take colourless transflective liquid, Dodecyl Bromide, isopropanol, catalyst obtained in step (3) in three-necked flask
In, reaction；
(5) after reaction, vacuum distillation removal isopropanol obtains crude product；
(6) recrystallization will be slightly produced, it is rear to dry, obtain product.
Preferably, lauryl amine in step (1), formic acid, formaldehyde molar ratio be 1:5:4.
Preferably, in step (2), the aqueous slkali is sodium hydroxide solution.
Preferably, after crude product being carried out recrystallization three times with ethyl acetate-isopropanol in the mixed solvent in step (6),
It is placed in dry in straight candied fruit baking oven.
Cation surface activating of the invention can be used for replacing traditional anionic surfactant, be applied to leather
There is the high color fastness of resistance to dry and wet, and the cationic surface active agent group containing chain in base, leather base can be made to be fully extended, make skin
Leather goods have more flexibility.
Specific embodiment
Below in conjunction with specific embodiment, technical scheme in the embodiment of the invention is clearly and completely described.
The present invention provides a kind of preparation method of leather high-effective cationic surfactant, comprising the following steps:
(1) certain lauryl amine is added into three-necked flask, is slow added into 85% formic acid solution, stirs, slow heating,
After being warming up to 85 DEG C, then 36% formalin is slowly added dropwise, reacts 8 hours；Wherein, lauryl amine, formic acid, formaldehyde molar ratio be
1:5:4.
(2) to fully reacting, liquid is poured into beaker, aqueous slkali is added into beaker, adjust its pH value be 10-12 it
Between；Has this, aqueous slkali is preferably sodium hydroxide solution.
(3) it after static a period of time, takes upper layer oily liquids to be evaporated under reduced pressure, obtains colourless transparent liquid；
(4) take colourless transflective liquid obtained in step (3), Dodecyl Bromide, isopropanol, catalyst in equipped with condenser pipe
In the three-necked flask of agitating device, heating slowly heats up, back flow reaction 5h；
(5) after reaction, vacuum distillation removal isopropanol obtains crude product；
(6) recrystallization will be slightly produced, it is rear to dry, obtain product.
Specifically, in one embodiment of the invention, crude product is mixed with ethyl acetate-isopropanol in step (6)
After being recrystallized three times in solvent, it is placed in dry in straight candied fruit baking oven.
Cation surface activating of the invention can be used for replacing traditional anionic surfactant, be applied to leather
There is the high color fastness of resistance to dry and wet, and the cationic surface active agent group containing chain in base, leather base can be made to be fully extended, make skin
Leather goods have more flexibility.
The above is a preferred embodiment of the present invention, it is noted that for those skilled in the art
For, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications are also considered as
Protection scope of the present invention.
