Description
The present invention is application number 200910090758.8, the dividing an application of denomination of invention " pentadecyl phenol polyethenoxy ether strong biodegradable tensio-active agent ".
Technical field
The present invention relates to a kind of tensio-active agent and preparation method thereof, especially relate to and take decarboxylation cashew nut shell crude oil and be raw material with the cardanol that its extracts, pentadecyl phenol polyethenoxy ether surface active agent and preparation method thereof between preparing with pentadecyl phenol between its major ingredient and reacting ethylene oxide.
Background technology
Tensio-active agent is a large class organic compound, and their character has characteristic: have the multiple excellent functions such as dispersion, wetting, infiltration, emulsification, solubilising, decontamination; Apply very flexible: can be widely used in the industries such as washing composition, weedicide, sterilant, plastics additive, emulsifying agent, wetting agent, coating, makeup, weaving, agricultural chemicals, leather, building materials, papermaking and oil field chemical, have very large use value.Along with the development of world economy and the developing of science and technology field, the development of tensio-active agent and application are very swift and violent.Whole world annual production is with 4～5% speed increment, and the consumption of global tensio-active agent in 2005, at 1,250 ten thousand tons, expects 2010 and can reach 1,700 ten thousand tons.The tensio-active agent output of China increases with 5～6% average growth rate per annum in recent years, by 2005, reaches 1,200,000 tons, expects 2010 and reaches 2,000,000 tons.
Tensio-active agent is through after using, and as sewage discharge, thereby through various channels in entered environment, therefore requires these organic components to degrade, in order to avoid accumulation causes harmful effect.The biological degradation of tensio-active agent is one of important indicator of its life cycle analysis, and a lot of countries all arrange this index, and as European Union points out, the degradation rate of environment-friendly type tensio-active agent must be more than 80%.The degree that a kind of organic chemicals can be resolved into simple organic molecule by microorganism is to determine that this chemical causes dangerous important factor to human body and environment.
Biological degradation is divided into basic biological degradation and final biological degradation.So-called final biological degradation refer to a kind of organic chemicals degradable be harmless final product, normally carbonic acid gas, water, biomass and inorganic salt.Except a few exceptions, can think that the product that tensio-active agent has experienced after biological degradation fast and is widely safe, this process has remarkable reduction for the toxicity of aquatic organism, and eliminated other possible harmful character.
Conventionally, tensio-active agent is divided into anion surfactant, cats product, amphoterics and nonionogenic tenside.The present invention take cashew nut shell oil as main raw material preparation table surface-active agent be nonionogenic tenside.Traditional nonionogenic tenside is by mineral raw material oil, and phenol through extracting is synthetic obtaining further.Its advantage is to have the abilities such as good water-soluble, wetting, washing, and shortcoming is that biodegradability is poor.The present invention having retained on the basis of original excellent properties, has greatly improved biodegradability just.
General for nonionogenic tenside the biological degradability of fatty alcohol-polyoxyethylene ether best, straight chained alkyl and with the alkyl of monomethyl side chain, biological degradability is similar, side chain increases, biological degradability variation.Alkylphenol polyoxyethylene particularly branched alkylphenol polyoxyethylene biological degradation is very poor, disabled in many countries; The degradation property of segmented copolymer is poorer.More growth degradation property is poorer be experimental results show that for the polyoxyethylene chain of nonionogenic tenside, the decomposition rate of the polyoxyethylene chain in such tensio-active agent is much slower than carbochain decomposition rate, while having polyoxyethylene and polypropylene chains in molecule, polypropylene chains can reduce decomposition rate.
