Description
[0010]尿素の酸性塩もこの点で、鉱酸と比較して、それらがはるかに良好な健康および安全プロファイル（皮膚に対する非腐食性、非発煙性、金属に対するより低い腐食性）を有するので、優れた用途を有することが示されてきた。さらに、尿素の酸性塩の固有酸強度は有機酸よりもかなり高く（０．２ｐＫａ対４ｐＫａ）、したがって二酸化炭素および関連するカルシウム塩を生成する、炭酸カルシウムスケールとの反応速度ははるかに速い。加えて、ＢＯＤおよびＣＯＤへの尿素の酸性塩の寄与は、有機酸によるよりもかなり低くなりうる（約３分の１から２分の１）。したがって、尿素の酸性塩はこの分野においてある程度の実用性を示している。 [0010] Acid salts of urea are also present in this regard, as they have a much better health and safety profile (non-corrosive to skin, non-fuming, less corrosive to metals) compared to mineral acids. , have been shown to have excellent applications. In addition, the intrinsic acid strength of urea acid salts is much higher than organic acids (0.2 pKa vs. 4 pKa) and thus the reaction rate with calcium carbonate scales to form carbon dioxide and related calcium salts is much faster. In addition, the contribution of urea acid salts to BOD and COD can be much lower (about 3 to 2 fold) than by organic acids. Accordingly, acid salts of urea have shown some utility in this field.
[0011]市販品として入手できる、最も普通に使用される尿素の酸性塩は、尿素塩化水素塩および尿素硫酸塩である。後者の化合物は、使用中に生成される硫酸カルシウムの低い溶解性のために、炭酸カルシウム除去に限定して使用される。にもかかわらず、これらの薬品は、小売ベースの浴室クリーナーから油井刺激に至る大規模工業デスケーリングまで、多用途および広範囲の用途で優れた実用性をもつことが示されている。 [0011] The most commonly used acid salts of urea that are commercially available are urea hydrochloride and urea sulfate. The latter compounds are of limited use for calcium carbonate removal due to the low solubility of the calcium sulfate produced during use. Nonetheless, these chemicals have been shown to have excellent utility in multiple uses and a wide range of applications, from retail-based bathroom cleaners to large-scale industrial descaling to oil well stimulation.
[0033]実例となる実施形態において、フッ酸を放出しない、複合シリケートのデスケーリングおよび溶解のための酸ベースのクリーニング組成物は、ヘキサフルオロリン酸、ヘキサフルオロジルコン酸およびヘキサフルオロチタン酸からなる群より選択されるフッ素含有酸と前記フッ素含有酸の酸性塩との組み合わせを含む。 [0033] In an illustrative embodiment, an acid-based cleaning composition for descaling and dissolution of complex silicates that does not release hydrofluoric acid consists of hexafluorophosphoric acid, hexafluorozirconic acid and hexafluorotitanic acid. Including combinations of fluorine-containing acids selected from the group and acid salts of said fluorine-containing acids.
[0034]実例となる実施形態において、前記酸性塩は、前記フッ素含有酸と、尿素、置換尿素、短鎖脂肪族アミン、短鎖オレフィン系アミド、芳香族アミド、ピロール、ピラゾールおよびインドールからなる群より選択される弱塩基との反応生成物を含む。 [0034] In an illustrative embodiment, said acid salt comprises said fluorine-containing acid and the group consisting of urea, substituted urea, short chain aliphatic amines, short chain olefinic amides, aromatic amides, pyrroles, pyrazoles and indoles. Including reaction products with weak bases that are more selected.
[0053]さらに、本明細書において記載し特許請求したフッ素化酸はすべて非常に強く、０よりかなり低いｐＫａを有するため、これらは各々、尿素（本質的に、非常に弱い塩基）および置換尿素のような化合物を用いてそれから酸性塩を生成する、優れた候補であろう。潜在的に用いることができそうな他の化合物は、短鎖、脂肪族、オレフィン系および芳香族系のアミドである。さらに、「オール」族の薬品はこの点で非常に有用でありえ、これらに限定されないがピロール、ピラゾールおよびインドールのような化合物の使用を含む。本明細書において、「酸性塩」という用語は一般的にこれらの化合物のことをいう。これは次には、皮膚に接触した場合に非有害である観点から安全なだけでなく、組織（とりわけ皮膚）に接触した場合に熱傷をもたらしうる強酸に関連する一般的な腐食性を著しく減少させるであろう、酸製品の製造を可能にするであろう。利用できる種々の用途における実用性のメカニズムは、製品が「そのまま」または酸性塩（フッ素化酸からケイ素またはアルミニウムのような酸化物へのフッ素移動）として存在するかどうかで同じであろう。酸性塩は単に、典型的な酸やけどの観点から、製品をより安全にするであろう。 [0053] Furthermore, since the fluorinated acids described and claimed herein are all very strong and have pKa's well below 0, they are urea (essentially a very weak base) and substituted ureas, respectively. would be an excellent candidate to use a compound such as to form an acid salt therefrom. Other compounds that could potentially be used are short chain, aliphatic, olefinic and aromatic amides. Additionally, the "ol" family of chemicals can be very useful in this regard, including but not limited to the use of compounds such as pyrroles, pyrazoles and indoles. As used herein, the term " acid salt " generally refers to these compounds. This, in turn, is not only safe in terms of being non-hazardous when in contact with skin, but also significantly reduces the general corrosiveness associated with strong acids that can cause burns when in contact with tissue (especially skin). It would allow the production of acid products that would allow The mechanism of utility in the various applications available will be the same whether the product is present "as is" or as an acid salt (fluorine transfer from a fluorinated acid to an oxide such as silicon or aluminum). An acid salt would simply make the product safer in terms of typical acid burns.
[0054]以上に照らして、本発明の目的は、別な方法ではｕＴＦＢ酸ベースの薬品により可溶化できなかったであろう、高度に複雑なシリケートおよびシリカの溶解を可能にするであろう、種々の金属、半金属または非金属のフッ素含有酸またはこれらのベース酸の酸性塩を提供することでありうる。これらの酸は、ＨＦフリーであるか、またはより低濃度のＨＦを含んでいてもよく、皮膚に接触したときにフッ素症／低カルシウム症、およびＨＦに関連する他の不利な健康および安全上の懸念をなくすかまたは減らすことによって、健康および安全プロファイルを改善する。さらに、これらのスケールの溶解は、地上用途（たとえばエバポレーターもしくはスクラバーデスケーリングまたは鉱山用途）および地下用途（たとえば地熱スケールまたは油田破砕／坑井刺激）の両方において行われるであろう。加えて、これらの技術は、バイオフィルムが覆ったまたは一体化して種々のスケールになった状況においても、大いに実用性を有するであろう。この技術は、バイオフィルムおよびスケールの両方の除去に有効であろう。同様に重要なことに、この技術は、ＨＦによって引き起こされうる環境への悪影響を避けるであろう。 [0054] In light of the above, it is an object of the present invention to enable the dissolution of highly complex silicates and silicas that otherwise could not be solubilized by uTFB acid-based chemicals.

In addition, these techniques will also have great utility in situations where biofilms are covered or integrated to various scales. This technique will be effective in removing both biofilm and scale. Equally important, this technique will avoid the adverse environmental impacts that can be caused by HF.
