Abstract
A synthesizing method of hexadecanol/octodecanol-mixed polyoxyethylene ether belongs to the filed of synthesizing technology of organic compounds. Hexadecanol/octodecanol-mixed polyoxyethylene ether is produced through polymerization of raw materials including mixed hexadecanol/octodecanol and ethylene oxide under the existence of a catalyst. The weight proportion of the mixed hexadecanol/octodecanol and ethylene oxide is 1:0.145-18.6; the catalyst is one of or a mixture containing more than one of solid sodium methylate, methanol solution of sodium methylate, KOH, NaOH, etc, and the addition thereof is 0.05-0.2 weight percent of prepared hexadecanol/octodecanol-mixed polyoxyethylene ether. Through rational determination of technological parameters and conditions such as raw material proportion, catalyst amount, polymerization temperature and time, etc., the method of the invention can have the advantages of mild reaction condition, low equipment requirement and high product yield and, in addition, has no impurity or pollutant production. The product has light color, good appearance, wide adjustable molecular weight range and high mutual modulation effect when in mixed application with products having other properties.
Description
Technical field
The present invention relates to a kind of synthetic method of hexade/octode mixing alcohol polyoxyethylene, belong to technical field of organic compound synthesis.
Background technology
Existing 16 or polyoxyethylene octadecanol uses all is single alcohol, the alcohol mixture product is seldom arranged, its single use properties has limited use range.
Summary of the invention
It is reasonable to the purpose of this invention is to provide a kind of technology, have better use properties the synthetic method of hexade/octode mixing alcohol polyoxyethylene.
The present invention is the synthetic method of hexade/octode mixing alcohol polyoxyethylene, is raw material with 16/18 alcohol mixtures and oxyethane, it is characterized in that carrying out polyreaction and make in the presence of catalyzer; The weight ratio of described 16/18 alcohol mixtures and oxyethane is 1: 0.145～18.6; Described catalyzer is a solid sodium methylate, methanol solution of sodium methylate, and KOH, the mixture of any one or more of NaOH etc., its add-on is 0.05～0.2% of the hexade/octode mixing alcohol polyoxyethylene weight percent that makes.
Described polymeric reaction temperature can be 120～180 ℃.
Described polymerization reaction time can be 5～20 hours.
The molecular weight of described hexade/octode mixing alcohol polyoxyethylene can be 353～3500g/mol.
The present invention compares by the analysis to existing polyether product synthetic method, through optimization design and repetition test research, rationally determined processing parameter and conditions such as proportioning raw materials, catalyst levels, polymeric reaction temperature, time, the reaction conditions gentleness, low for equipment requirements.And the yield height does not have impurity to generate environmental friendliness.The hexade/octode mixing alcohol polyoxyethylene lighter color that makes by the present invention, appearance property is good, the scope of adjustable csa molecule amount is big: hydroxyl value 159.0～27.7mgKOH/g, molecular weight 353～3500g/mol (molecular weight=56110/ hydroxyl value) mixes the intermodulation height that uses with other performance products.Have good emulsification, level dyeing performance, warm viscosity, biological degradability.Product is non-ionic type in alkalescence and neutral medium, be cationic in acidic medium; The levelling agent that is used for acidic complex dye can reduce dye bath sulfuric acid consumption, reduces the fabric strength damage; Also can make neutral dye, the levelling agent of vat dyes, the stripping agent of wool, polyamide fabric etc.
