| titleOfInvention | Lignose alcohol ether carboxylate surfactant and preparation method thereof |
| abstract | The present invention discloses a lignin alcohol ether carboxylate novel surfactant preparation method. 100 weight proportions of lignin alcohol ether and base catalyst with 1 to 1.2 times of the weight proportions of the lignin alcohol ether react for 30 to 60 minutes under 90 to 110 DEG C; low-boiling substance is removed by decompressing under subtractive 0.1MP; halogenated acid with the substance quantity of 1.2 to 1.5 times of the lignin alcohol ether is added to react for 4 to 8 hours to obtain the lignin alcohol ether carboxylate. In the reaction steps, the lignin alcohol ether is prepared by self; the halogenated acid can be any one of 2-chloropropionic acid, chloroacetic acid, 2-bromo propionate or bromoacetic acid; the base catalyst is KOH or NaOH. In the characterization of the lignin alcohol ether carboxylate, foam performance water hardness is 150 multiplied by 10<subtractive 6>ppm as being measured by a Rockwell latherometer; sample content is 0.25 percent under 40 DEG C, the foam height is measured as the start height of 150mm; the foam height is 130mm after 5 minutes; when surface tension (delta) sample contents are 0.01 percent and 0.05 percent respectively, the surface tensions are respectively 57.2mN/m and 51.2mN/m; critical micelle concentration (CMC) measured value is 5.0g/L. |
