Definitions
- the present invention relates to chemiluminescent compositions comprising at least two constituents (a) and (b) in reactive isolation to each other.
- Component (a) contains an oxalate ester in combination with a phosphate ester solvent.
- Component (b) contains a peroxide activator in combination with a catalyst and a solvent.
- the composition also contains a fluorescer which can be present m any one of constituents (a) or (b) or can be distributed over both constituents.
- Such compositions produce, upon mixing of the individual constituents, a cnemiluminescent light, frequently termed "cold light", which can last a few hours.
- compositions are well known and have been around for a long t me, several decades.
- Such compositions generally comprise, on one side, a mixture of an oxalate ester in a suitable solvent ana, m a non-reactive isolation, a mixture of the peroxide component and the catalyst.
- One or both of the constituents, often the oxalate constituent comprise one or several fluorescers.
- the selection of the fluorescer determines qualitative and quantitative properties, among others the color, of the chemiluminescent light produced.
- Chemiluminescent systems are commercially available for example in the form of plastic light sticks and can be activated by bending to thus rupture the internal container surrounding the individual constituents and provoke the mixing of the constituents.
- Chemiluminescent technology can be used for a variety of applications such as in baits for industrial fishing.
- the chemiluminescent technology generally is summarized m C&EN, January 18, 1999, page 65, by Elisabeth Wilson.
- US-A-3.816.326 describes selected substituted carboxymethyl oxalates and the use of such esters as chemiluminescent materials in admixture with solvents, for example substituted phthalates.
- US-A-5.597.517 also relates to conventional chemiluminescent compositions comprising a particular solvent, namely: a propylene glycol dihydrocarbyl ether containing one to three propylene moieties and each hydrocarbyl moiety contains up to eight carbon atoms.
- compositions containing, as a first constituent, an oxalate ester m combination/admixture with a narrowly and specifically defined phosphate ester solvent, and as a second constituent a peroxide-catalyst combination.
- a fluorescer shall be added to any one of the constituents or can be distributed over both constituents.
- multi-component chemiluminescent composition comprising two reactively- lsolated constituents which, upon admixture, can produce beneficially improved light.
- compositions herein comprise at least two constituents (a) and (b) in reactive isolation to each other whereby constituent: (a) contains an oxalate ester in combination with a phosphate ester solvent having the formula:
- Ri , R 2 and R 3 are independently selected from C-,- ⁇ -alkyl, aryl, C ⁇ - 0 -alkylaryl, Ci- ⁇ - alkoxy-C ⁇ -6-alkyl, C ⁇ - 6 -alkoxyaroyl and mixtures thereof;
- a fluorescer which can be present in any one of the (a) or b) constituents or can be distributed over both constituents. It was found, m particular, that specific phosphate ester solvents provide chemiluminescent compositions capable of delivering superior light efficiency, particularly improved brightness and extended useful lifetime. The beneficial performance is, in part, believed to originate from the unexpected light synergism of the phosphate solvent as compared to current solvents such as phthalate- and dihydrocarbyl-derivatives .
- the oxalate ester component can be represented by all known species which are known to be suitable for use in chemiluminescent compositions. Examples of the like oxalates are described in US-patents N° . : 3.597.362; 3.749.679; and 5.597.517. Examples of suitable oxalates herein are particularly recited in US patent 5.597.517, column 3, lines 43-56.
- Preferred oxalate esters herein are represented by bis (2, 4, 5-trichloro-6- carboxypentoxyphenyl) oxalate , hereinafter “CPP- oxalate”, and bis (2, 4, 5-trichlorophenyl) oxalate, hereinafter “TCP-oxalate” .
- the oxalate component is generally used in the art-established levels and ratios.
- the oxalate concentration, on a molar basis, in the oxalate/solvent combination (constituent (a) ) may, for example, vary from 0.01M to 1.5M.
- the phosphate ester solvent can be represented by all species embraced by the structural formula recited above. Generally preferred phosphate ester species are represented by alkyl diaryl phosphates and triaryl phosphates and mixtures thereof in a weight ratio of alkyl diaryl to triaryl of 97 : 3 to 50 : 50. Other preferred phosphate solvent species carry the following Ri, R 2 and R 3 substituents : C ⁇ -io-alkyl, C ⁇ --alkylaryl, C ⁇ - 4 - alkoxy-C ⁇ -4-alkyl and C ⁇ - 4 -alkoxyaroyl.
- Very preferred phosphate ester species are represented by C 8 -.o- alkyldiarylphosphates and C 3 -- ⁇ -alkylaryldiarylphosphates or mixtures of such very preferred species in a weight ratio of from (alkyldiaryl : alkylaryldiaryl ) 90 : 10 to 97 : 3.
- Other very preferred phosphate ester solvent species can be represented by octyldiphenylphosphate and para-tertiarybutylphenyldiphenyl phosphate or mixtures of such species in a weight ratio (octyldiphenyl : butylphenyldiphenyl) of from 95 : 5 to 60 : 40.
- the oxalate ester component represents, expressed based on the sum of the oxalate ester and the phosphate ester solvent being 100%, from 1% - 40%, preferably from 3% - 35%, more preferably from 6% : 30%.
- the levels of oxalate constituent (a) and peroxide activator constituent (b) can vary in the range of from ((a) : (b) ) 15 : 85 to 85 : 15.
- the composition in addition, contains the fluorescer in a level generally with the range of from 0.001% to 1.0% based on the sum of constituents (a) and (b) and the fluorescer.
- the constituents (a) and (b) are in reactive isolation i.e. these reactants are, in the composition, physically isolated for exmple with the aid of plastic barriers or equivalent means which thus block any contact of the constituents before the actual usage.
- the separating means (barriers) can be broken by pressure or other conventional approaches well-known and generally applied in connection with using cold light compositions.
- Suitable peroxide activators, catalysts and solvents therefor are well known in the relevant domain of technology and can be used in the art- established levels and proportions (ratios) .
- Precise species and level indications for use herein are known from US-patent 5.597.517 column 3, line 61 to column 4, line 55.
- phosphate ester solvents, having the formula set forth in claim 1 can be used in total or partial e.g. from about 40 % to 90%, replacement of the solvents recited in the referenced passage (col. 4, lines 1-22).
- the molar concentration of the peroxide component (in the peroxide- activator) in the solvent used for constituent (b) can be in the range of from 0.005M to 3.0M.
- CPP-oxalate bis (2, 4, 5-tr ⁇ chloro- 6-carboxypentoxyphenyl) oxalate
- the maximum concentration of CPP-oxalate was measured at -10°C. The results found were as follows:
- Solvent dibutyl phthalate; stable solution was obtained at a maximum concentration of 125 g/1 (-10°C) .
- Solvent butylbenzoate; stable solution was obtained at a maximum concentration of 160g/l (-10°C) ;
- Solvent mixture of diphenyloctyl phosphate and para- tertiary-butylphenyldiphenyl phosphate in a weight ratio of (octyldiphenyl : butylphenyldiphenyl) of 95 : 5; stable solution was obtained at a maximum concentration of 250 g/1 (-10°C) .
- An activator component was prepared by mixing: dimethylphthalate 0.8 1; t-butanol 0.2 1; sodium salicylate 180 mg; and hydrogen peroxide (85%) 50 g.
- composition (3) of this invention in particular extended useful lifetime and improved brightness, as compared to actual art executions (comparative 1 and 2) .
