Benzoesan sodu

Nazwa: Benzoesan sodu
Synonimy: sól sodowa kwasu benzoesowego, Sodium benzoate
Gatunek: Czysty
Czystość: Czysty bez domieszek
Wzór chemiczny: NaC7H5O2

Benzoesan sodu, C6H5COONa jest organicznym związkiem chemicznym. Jest to sól sodowa kwasu benzoesowego, którą stosuje się w roli konserwanta. Na skalę przemysłową uzyskuje się ją syntetycznie. Benzoesan sodu posiada właściwości bakteriostatyczne oraz fungistatyczne, hamuje rozwój drożdży, pleśni oraz bakterii masłowych, octowych i (w mniejszym stopniu) mlekowych. Jego aktywność zwiększa się dzięki obecności dwutlenku siarki, dwutlenku węgla, soli kuchennej, cukru i kwasu sorbinowego (lub jego soli).

Występowanie
Benzoesan sodu występuje w postaci anionu benzoesanowego głównie w jagodach, ale także w niewielkich ilościach w grzybach, cynamonie, żurawinie, goździkach i niektórych produktach mlecznych (efekt fermentacji bakteryjnej).

Zastosowanie beznoesanu sodu:
- szeroko stosowany w przemyśle środek do konserwacji,
- pełni również rolę solubilizatora,
- jest składnikiem zapobiegającym korozji w płynach do przechowywania narzędzi chirurgicznych,
- jest składnikiem pomocniczych środków diagnostycznych,
- ma szerokie zastosowanie w pirotechnice amatorskiej oraz komercyjnej. Na jego bazie wykonuje się na przykład mieszaninę świszczącą (pot. świszczała lub SSA). Jest też dobrym żółtym barwnikiem płomienia (dzięki zawartości sodu) wytwarzającym podczas spalania duże ilości gazów.
