Dibenzothiophene (DBT, diphenylene sulfide) is the organosulfur compound consisting of two benzene rings fused to a central thiophene ring. It has the chemical formula C 12 H 8 S. It is a colourless solid that is chemically somewhat similar to anthracene .
Dibenzofuran is a relatively non-toxic compound as evidenced by rats being unaffected after a 200-day diet consisting of 0.025 – 0.4% of DBF. [1] The polychlorinated dibenzofurans are however among the potentially toxic dioxins and dioxin-like compounds.
The high reactivity of thiophene toward sulfonation is the basis for the separation of thiophene from benzene, which are difficult to separate by distillation due to their similar boiling points (4 °C difference at ambient pressure).
Melting point: 3.6 °C (38.5 °F; 276.8 K) Boiling point: 298 °C (568 °F; 571 K) Hazards ... It is classified as an ether derived from benzyl alcohol.
Melting point: 69 °C (156 °F; 342 K) Boiling point: 298 °C (568 °F; 571 K) ... Diphenylmethanol is an irritant to the eyes, skin and respiratory system.
The extended conjugation of the acrylate portion of the molecule absorbs UVB and short-wave UVA (ultraviolet) rays with wavelengths from 280 to 320 nm, [1] protecting the skin from direct DNA damage. The ethylhexanol portion is a fatty alcohol , adding emollient and oil-like (water resistant) properties.
A 42-year-old Belgian tourist was taking a short walk Saturday in the sand dunes in 123-degree heat when he either broke or lost his flip-flops, putting his feet into direct contact with the ...
Benzyl benzoate can be a skin irritant when used as a topical scabicide. [7] Overdose can result in blistering and hives or a rash can occur as an allergic reaction. [12] [13] As an excipient in some testosterone-replacement injectable medications, benzyl benzoate has been reported as a cause of anaphylaxis in a case in Australia. [14]
