Definition
ChEBI: A member of the class of phenols that is phenol carrying a butan-2-yl group at position 2.
General Description
Clear colorless liquid.
Air & Water Reactions
Insoluble in water.
Reactivity Profile
Phenols, such as 2-sec-Butylphenol, do not behave as organic alcohols, as one might guess from the presence of a hydroxyl (-OH) group in their structure. Instead, they react as weak organic acids. Phenols and cresols are much weaker as acids than common carboxylic acids (phenol has Ka = 1.3 x 10^[-10]). These materials are incompatible with strong reducing substances such as hydrides, nitrides, alkali metals, and sulfides. Flammable gas (H2) is often generated, and the heat of the reaction may ignite the gas. Heat is also generated by the acid-base reaction between phenols and bases. Such heating may initiate polymerization of the organic compound. Phenols are sulfonated very readily (for example, by concentrated sulfuric acid at room temperature). The reactions generate heat. Phenols are also nitrated very rapidly, even by dilute nitric acid.
Hazard
Skin, eye, and upper respiratory tract irri-
tant.
Health Hazard
o-sec-Butylphenol is a skin, eye,
and respiratory irritant.
Acute occupational exposures have resulted
in mild respiratory irritation as well as
skin burns.
Fire Hazard
2-sec-Butylphenol is combustible.
Flammability and Explosibility
Notclassified
Safety Profile
A poison by
intraperitoneal and intravenous routes.
Moderately toxic by ingestion and skin
contact. A severe skin and eye irritant.
Combustible when exposed to heat or
flame. To fight fire, use foam, spray, CO2,
dry chemical. When heated to
decomposition it emits acrid and irritating
fumes. See also PHENOL and other butyl
phenols
Potential Exposure
Butylphenols may be used as intermediates in manufacturing varnish and lacquer resins; as a
germicidal agent in detergent disinfectants; as a pour point
depressant, in motor-oil additives; de-emulsifier for oil;
soap-antioxidant, plasticizer, fumigant, and insecticide

Corrosive material
Incompatibilities
Vapors may form explosive mixture with
air. These phenol/cresol materials can react with oxidizers;
reaction may be violent. Incompatible with strong reducing
substances such as hydrides, nitrides, alkali metals, and sulfides. Flammable gas (H2) is often generated, and the heat
of the reaction may cause the gas to ignite and explode.
Heat is also generated by the acid-base reaction with bases;
such heating may initiate polymerization of the organic
compound. React with boranes, alkalies, aliphatic amines,
amides, nitric acid, sulfuric acid. Phenols are sulfonated
very readily (for example, by concentrated sulfuric acid at
room temperature). These reactions generate heat. Phenols
are also nitrated very rapidly, even by dilute nitric acid and
can explode when heated. Many phenols form metal salts
that may be detonated by mild shock
Check Digit Verification of cas no
The CAS Registry Mumber 89-72-5 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 8 and 9 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 89-72:
(4*8)+(3*9)+(2*7)+(1*2)=75
75 % 10 = 5
So 89-72-5 is a valid CAS Registry Number.

METHOD FOR PREPARING P-HYDROXYMANDELIC COMPOUNDS IN STIRRED REACTORS
-
, (2017/07/14)
The process allows the preparation of a p-hydroxymandelic compound, comprising at least one step of condensation of at least one aromatic compound bearing at least one hydroxyl group and whose para position is free, with glyoxylic acid, the condensation reaction being performed in at least one reactor equipped with at least one mixing means, the specific mixing power being between 0.1 kW/m3 and 15 kW/m3. In addition, the invention also relates to a process for preparing a 4-hydroxyaromatic aldehyde by oxidation of this p-hydroxymandelic compound.
Process for functionalising a phenolic compound carrying an electron-donating group
-
, (2008/06/13)
The invention concerns a method for functionalizing a phenolic compound bearing an electron-donor group, in said group para position, inter alia a method for the amidoalkylation of a phenolic compound bearing an electron-donor group, and more particularly, a phenolic compound bearing an electron-donor group preferably, in the hydroxyl group ortho position. The method for functionalizing in para position with respect to an electron-donor group carried by a phenolic compound is characterised in that the phenolic compound bearing an electron-donor group is subjected to the following steps: a first step which consists of protecting the hydroxyl group in the form of a sulphonic ester function; a second step which consists in reacting the protected phenolic compound with an electrophilic reagent; optionally, a third step deprotecting the hydroxyl group.
A fluorescence detection scheme for capillary electrophoresis of N- methylcarbamates with on-column thermal decomposition and derivatization
Wu, Yuan Sheng,Lee, Hian Kee,Li
, p. 1441 - 1447 (2007/10/03)
This paper describes a fluorescence detection method for N- methylcarbamate (NMC) pesticides in micellar electrokinetic chromatography (MEKC) separation. Fulfillment of the fluorescence detection hinged on the discovery that quaternary ammonium surfactants (particularly cetyltrimethylammonium bromide, CTAB), besides serving as hydrophobic pseudophases in MEKC, are also capable of catalyzing the thermal decomposition of NMCs to liberate methylamine. Thus, a multifunctional MEKC medium consisting of borate buffer, CTAB, and derivatizing components (o- phthaldialdehyde/2-mercaptoethanol) was formulated, which allowed first normal MEKC separation, subsequent thermal decomposition, and finally in situ derivatization of NMCs. With careful optimization of the operation conditions, fluorescence detection of 10 NMC compounds was achieved, with column efficiencies typically higher than 50 000 and detection limits better than 0.5 ppm. The present work represents an unprecedented effort in capillary electrophoresis (CE), in which an intact capillary was consecutively utilized as chambers for separation, decomposition, derivatization, and detection, without involving any interfacing features. The success in the implementation of such a detection system resulted in strikingly simple instrumentation as compared with the traditional postcolumn fluorescence determination of NMCs by reversed-phase HPLC. Similar protocols should be workable in the determination of a wide range of pesticides and pharmaceuticals in CE formats.
