Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides novel compounds with builder or active properties, [41]
The present invention relates to a phosphorus-free cleaning composition containing the present invention as an ingredient.

Phosphate, which is widely used as a builder for detergents, especially tripolyphosphate, has excellent properties as a builder, but it is also cited as one of the causes of water pollution due to so-called eutrophication. . For this reason, there is a trend towards phosphorus-free detergents, which do not use the above-mentioned phosphates, and currently the amount of phosphorus-free detergents used exceeds that of phosphorus detergents.

Recently, synthetic zeolites have been widely used as a builder to replace sodium tripolyphosphate, but due to their water insolubility, they tend to precipitate during drainage.3 Various studies have also been conducted on other organic zeolites, but there are problems. The reality is that there are many points 1, and the desired conditions for a builder are (1)
Safety for humans + J1 (2) Safety for the environment (3)
) It has excellent functions as a builder, (4) It is water-soluble, (5) It has the ability to coordinate metals or metal ions, and (6) It probably does not contain nitrogen or phosphorus as much as possible.

In view of the above circumstances, the present inventor has conducted extensive research into builders that do not contain nitrogen or phosphorus, have good hydrolyzability and/or biodegradability, and have excellent metal sequestering ability and resolution, such as C and H lucium ions, and have developed a new builder. It has been found that polyether carbonate derivatives are suitable for this purpose. At the same time, if the balance between hydrophobic and hydrophilic groups is adjusted, it is useful as a general anionic activator for forming ester bonds.

That is, the present invention relates to the following general formulas (1), (2) and (3)-3o3X (

Polyether carbonate, which is an intermediate for the compound of the present invention, has hydrocarbon residues having 2 or more carbon atoms (saturated, unsaturated, linear,

By telomerization polymerization, 'C' is obtained.

Telogens include ethylene glycol, di-T tylene glycol, propylene glycol, dibu [1 pyrene glycol, butylene glycol, alcohols with 4 to 20 carbon atoms, diethylene glycol monomethyl [=tyl, J
Examples include ethylene glycol monoethyl ether, ethylene glycol monobutyl ether, diethylene glycol monobutyl ether, and glycerin.

lli! ! Oxidation can be carried out using conventional chlorosulfonic acid, tIfic anhydride, fuming sulfuric acid, or the like. 1. If necessary, a solvent such as carbon tetrachloride may be used. Neutralizing agents include Na, N+-14, amines, and others, but are not particularly limited, but are preferred from the viewpoint of water solubility.

Furthermore, the terminal may be made into a sulfonate by using monothorium isethyl acid, or the terminal may be made into a sodium J rubonate by using sodium monochloroacetate.

Polyether carbonate is originally insoluble in water, but by making it into an anionic active agent type, its water solubility increases and various applications become possible. In addition, it is also possible to apply the auxiliary action of the surfactant to a cleaning agent as an active agent.

To carbonate obtained using dylene glycol monoethyl ether, glycerin, etc.? The anionic activator is
The surface tension is not low, and although it does not show much activity, it has excellent oxidizing power and dispersion power.In addition, when octyl, lauryl, or myristyl alcohol is used as a telogen, it functions as an anionic activator. 1.More? The first thing to note is that conventional ether-type anionic surfactants have poor biodegradability due to their ethylene oxide chains, do not lose their surface activity once used, and may sometimes cause pollution. Since the compounds of the invention are easily hydrolyzed and lose their surface activity at pH 9.5 or higher, more effective developments can be considered by utilizing this property.

This activator is a conventional anionic activator, a nonionic activator,
Amphoteric active agents, cationic active agents, such as Argyl 11! acid ester salt, alkyl ether sulfate ester salt, alkylbenzene sulfonate, α-olefin sulfonate, α-sulfo fatty acid ester salt, polyoxyethylene alkyl (alkylene) ether, polyoxyethylene alkyl 7--thyl , alkyl betaine, alkylimidazolinium betaine, mono- and dialkyl ammonium halides, mono- and dialkylpyridinium halides, mono- and dialkylbenzalkonium halides, etc., or of course can be used alone. In addition to its function as a cleaning agent, it can also function as a solubilizer, dispersant, wetting agent, emulsifier, metal oil agent, etc., so it can be applied to fields such as textiles, metals, emulsion polymerization, and architecture. It is possible.

Specific examples are shown below, but the invention is not limited thereto.
