DESCRIZIONE dell'invenzione industriale dal titolo: "Procedimento per la riduzione delle contaminazioni di composti organici volatili, in particolare formaldeide” DESCRIPTION of the industrial invention entitled: "Process for reducing contamination of volatile organic compounds, in particular formaldehyde"
DESCRIZIONE DESCRIPTION
La presente invenzione si riferisce a un procedimento di riduzione delle contaminazioni di superfici da composti organici volatili, altresì indicati come VOC (acronimo per “volatile organic compounds”), in particolare formaldeide. The present invention relates to a process for reducing surface contamination by volatile organic compounds, also referred to as VOC (acronym for “volatile organic compounds”), in particular formaldehyde.
La formaldeide (chiamata anche aldeide formica o metanale) è la più semplice delle aldeidi. La sua formula chimica è CH2O, ed il suo numero CAS è 50-00-0. In soluzione acquosa al 37% è commercialmente nota anche con il nome di formalina o formolo. Formaldehyde (also called formic or metanaldehyde) is the simplest of the aldehydes. Its chemical formula is CH2O, and its CAS number is 50-00-0. In 37% aqueous solution it is commercially known also with the name of formalin or formol.
La formaldeide è notoriamente un potente battericida. Per questo motivo, in soluzione acquosa trova largo impiego come disinfettante per uso domestico e viene inoltre utilizzata come battericida nella produzione di tessuti a livello industriale. Formaldehyde is known to be a powerful bactericide. For this reason, in aqueous solution it is widely used as a disinfectant for domestic use and is also used as a bactericide in the production of fabrics at industrial level.
Soluzioni di formaldeide vengono anche utilizzate per conservare campioni di materiale biologico, nonché nelle tecniche di imbalsamazione. Formaldehyde solutions are also used to preserve biological material samples, as well as in embalming techniques.
La formaldeide viene altresì utilizzata in soluzione acquosa (forma nella quale prende il nome di “formalina”) per la produzione di vaccini, sia per produrre anatossine (o tossoidi), ossia tossine che perdono la tossicità ma mantengono l’immunogenicità, a partire da tossine batteriche, sia per produrre vaccini basati su microrganismi uccisi. Formaldehyde is also used in aqueous solution (form in which it takes the name of "formalin") for the production of vaccines, both to produce anatoxins (or toxoids), ie toxins that lose toxicity but maintain immunogenicity, starting from bacterial toxins, both to produce vaccines based on killed microorganisms.
La maggior parte della formaldeide prodotta è comunque destinata alla produzione di polimeri e di altri composti chimici. La formaldeide, a seguito della reazione con il fenolo, polimerizza dando la bachelite, una resina termo-indurente. In maniera analoga, la formaldeide reagisce con l'urea e la melammina, le cui resine trovano impiego come laminati plastici, adesivi e schiume isolanti. However, most of the formaldehyde produced is destined for the production of polymers and other chemical compounds. Formaldehyde, following the reaction with phenol, polymerizes giving Bakelite, a thermosetting resin. Similarly, formaldehyde reacts with urea and melamine, the resins of which are used as plastic laminates, adhesives and insulating foams.
La formaldeide è anche un reagente impiegato per produrre altri composti organici, molti dei quali sono polioli, come la pentaeritrite. Formaldehyde is also a reagent used to make other organic compounds, many of which are polyols, such as pentaerythritol.
La formaldeide è identificata dalla sigla E 240 come additivo alimentare, in particolare con la funzione di conservante. In effetti, la formaldeide è presente nel fumo di legno ed è, insieme ai polifenoli, responsabile della conservazione dei prodotti alimentari affumicati. Formaldehyde is identified by the initials E 240 as a food additive, in particular with the function of a preservative. Indeed, formaldehyde is present in wood smoke and is, together with polyphenols, responsible for the preservation of smoked food products.
Insieme all'urea, la formaldeide è anche impiegata come vernice collante di pannelli in legno di truciolato, nobilitato o Medium-density fibreboard (MDF). Essa è inoltre contenuta nei pannelli fonoassorbenti dei controsoffitti e nelle pareti divisorie degli uffici open space nei quali, nel corso degli anni, tende a volatilizzarsi nell'ambiente circostante. Together with urea, formaldehyde is also used as an adhesive paint for chipboard, melamine or Medium-density fibreboard (MDF) panels. It is also contained in the sound-absorbing panels of the false ceilings and in the partition walls of the open space offices in which, over the years, it tends to evaporate into the surrounding environment.
Questa sostanza viene utilizzata anche per la produzione di isoprenolo. Nella tintura tessile, è usata nell'applicazione con i naftoli per dare maggiore stabilità alle soluzioni naftoliche e nel trattamento successivo di alcune tinture ottenute con coloranti diretti con lo scopo di migliorarne le solidità all'acqua ed ai lavaggi in generale. This substance is also used for the production of isoprenol. In textile dyeing, it is used in application with naphthols to give greater stability to naphtholic solutions and in the subsequent treatment of some dyes obtained with direct dyes with the aim of improving their fastness to water and washing in general.
Dato il largo impiego di resine derivate dalla formaldeide nelle produzioni di manufatti, rivestimenti e schiume isolanti, che tendono a rilasciare col tempo molecole di formaldeide nell'ambiente, quest’ultima è uno dei più diffusi inquinanti di interni. A concentrazioni nell'aria superiori a 0,1 ppm, la formaldeide può irritare per inalazione le mucose e gli occhi. L'ingestione o l'esposizione a quantità consistenti di formaldeide sono potenzialmente letali: in particolare, la sua cancerogenicità è stata accertata sui roditori, dove provoca un tasso di incidenza di cancro al naso ed alla gola superiori al normale. La formaldeide è infatti in grado di interferire con i legami tra DNA e proteine. Given the wide use of resins derived from formaldehyde in the production of products, coatings and insulating foams, which tend to release molecules of formaldehyde into the environment over time, the latter is one of the most common indoor pollutants. At concentrations in air above 0.1 ppm, formaldehyde can irritate mucous membranes and eyes by inhalation. Ingestion or exposure to large quantities of formaldehyde are potentially lethal: in particular, its carcinogenicity has been ascertained in rodents, where it causes a higher than normal incidence rate of nose and throat cancer. In fact, formaldehyde is able to interfere with the bonds between DNA and proteins.
L'Associazione Internazionale per la Ricerca sul Cancro (IARC) sin dal 2004 ha inserito la formaldeide nell'elenco delle sostanze considerate con certezza cancerogene per la specie umana. Se le concentrazioni di formaldeide presenti normalmente all'interno degli edifici sono generalmente basse e quindi non particolarmente preoccupanti, vanno accuratamente valutati i rischi per gli addetti alle lavorazioni industriali che impiegano formaldeide. The International Association for Research on Cancer (IARC) since 2004 has included formaldehyde in the list of substances considered with certainty carcinogenic for the human species. If the concentrations of formaldehyde normally present inside buildings are generally low and therefore not particularly worrying, the risks for industrial workers who use formaldehyde must be carefully assessed.
L'Organizzazione Mondiale della Sanità ha indicato, come limite massimo di concentrazione accettabile di formaldeide in casa, 100 µg/m<3 >(pari a 0,1 parti per milione - ppm). The World Health Organization has indicated, as the maximum limit for the acceptable concentration of formaldehyde in the home, 100 µg / m <3> (equal to 0.1 parts per million - ppm).
Dal 1º gennaio 2016, la formaldeide è passata dalla classificazione di "sospettato di provocare il cancro" a "può provocare il cancro" (Regolamento (UE) N. 605/2014). From 1 January 2016, formaldehyde has passed from the classification of "suspected of causing cancer" to "can cause cancer" (Regulation (EU) No. 605/2014).
Vi è dunque la necessità di mettere a disposizione un procedimento atto a ridurre le concentrazioni di composti organici volatili altamente pericolosi per la salute umana quando inalati, in particolare di formaldeide. Tale necessità è particolarmente sentita con riferimento alla igienizzazione di superfici contaminate con residui di VOC, in particolare residui di formaldeide. There is therefore the need to make available a process suitable for reducing the concentrations of volatile organic compounds that are highly dangerous for human health when inhaled, in particular of formaldehyde. This need is particularly felt with reference to the sanitation of surfaces contaminated with VOC residues, in particular formaldehyde residues.
Tale necessità è stata ora soddisfatta grazie alla presente invenzione, che mette a disposizione un procedimento di igienizzazione di superfici contaminate con residui di VOC, avente le caratteristiche indicate nella rivendicazione 1 che segue. This need has now been satisfied thanks to the present invention, which provides a process for sanitizing surfaces contaminated with VOC residues, having the characteristics indicated in claim 1 below.
Preferibilmente, le superfici contaminate che vengono igienizzate con il procedimento dell’invenzione sono le superfici di alcuni oggetti e strumenti che entrano tipicamente in contatto con formaldeide, come ad esempio, ma non esclusivamente, cappe di aspirazione a flusso laminare per laboratori e contenitori per biopsie. Preferably, the contaminated surfaces that are sanitized with the process of the invention are the surfaces of some objects and instruments that typically come into contact with formaldehyde, such as, but not exclusively, laminar flow suction hoods for laboratories and containers for biopsies. .
Il procedimento dell’invenzione consente vantaggiosamente di abbattere le concentrazioni di VOC, in particolare formaldeide, sulle superfici trattate, mediante ossidazione ad opera di una soluzione acquosa clorossidante che viene spruzzata, nebulizzata o atomizzata sulle superfici da igienizzare. The process of the invention advantageously allows to reduce the concentrations of VOC, in particular formaldehyde, on the treated surfaces, by oxidation by an aqueous chlorioxidant solution that is sprayed, nebulized or atomised on the surfaces to be sanitized.
Una soluzione acquisa clorossidante di per sé nota è l’anolyte. Essa viene convenzionalmente prodotta all’anodo mediante elettrolisi di una soluzione acquosa satura di cloruro di sodio (NaCl) o cloruro di potassio (KCl). La soluzione prodotta per elettrolisi di una soluzione acquosa satura di cloruro di sodio (NaCl) o cloruro di potassio (KCl) contiene cloro attivo, prevalentemente sotto forma di ione ipoclorito (ClO-) e acido ipocloroso (HClO). An aqueous chlorioxidant solution known per se is anolyte. It is conventionally produced at the anode by electrolysis of a saturated aqueous solution of sodium chloride (NaCl) or potassium chloride (KCl). The solution produced by electrolysis of a saturated aqueous solution of sodium chloride (NaCl) or potassium chloride (KCl) contains active chlorine, mainly in the form of hypochlorite ion (ClO-) and hypochlorous acid (HClO).
In una forma di realizzazione preferita, il procedimento dell’invenzione prevede l’impiego della suddetta soluzione acquosa clorossidante, ovvero anolyte, con una concentrazione tra i 150 e 900 ppm e ad un pH compreso tra 4 e 7,5. In a preferred embodiment, the process of the invention provides for the use of the aforementioned aqueous chlorioxidant solution, or anolyte, with a concentration between 150 and 900 ppm and at a pH between 4 and 7.5.
In un’ulteriore forma di realizzazione preferita, l’anolyte utilizzata nel procedimento di igienizzazione dell’invenzione è anolyte stabilizzata, ottenuta mediante aggiunta alla soluzione prodotta all’anodo di un agente stabilizzante scelto dal gruppo che consiste di acido cloridrico (HCl) da 50 a 250 mg/l, acido solforico (H2SO4) da 50 a 350 mg/l, acido fosforico (H3PO4) da 50 a 500 mg/l, acido periodico (HIO4) da 10 a 1000 mg/l, cloruro di sodio (NaCl) da 1 a 30 g/l, e qualsiasi loro combinazione. In a further preferred embodiment, the anolyte used in the sanitation process of the invention is stabilized anolyte, obtained by adding to the solution produced at the anode of a stabilizing agent selected from the group consisting of 50 hydrochloric acid (HCl). to 250 mg / l, sulfuric acid (H2SO4) from 50 to 350 mg / l, phosphoric acid (H3PO4) from 50 to 500 mg / l, periodic acid (HIO4) from 10 to 1000 mg / l, sodium chloride (NaCl ) from 1 to 30 g / l, and any combination thereof.
Grazie alla presente invenzione, è stato messo a disposizione un procedimento di igienizzazione di superfici in grado di ossidare i vapori di formaldeide rendendo più sicuro l’ambiente di lavoro, che garantisce la sicurezza sanitaria e che al tempo stesso è economico e realizzato con materiali naturali (acqua e sale).
