Acute Exposure:

Oral LD50 : 1.8 g/kg (rats); slightly toxic to animals.

Dermal LD50 : 4.0 g/kg (rabbits); slightly toxic to animals by absorption.
Corrosive to skin.

Inhalation LC50 : Moderately toxic to animals (approximate inhalation
LC50, rats, 6 hrs.: 400 ppm.)

Eyes : Corrosive.

產品名稱: Acetic anhydride
MSDS 炭碼: 5
材料炭碼: 80005
公垦日期�? 02/02/2006
Mutagenicity : In vitro , no evidence of mutagenicity in Ames test
(bacteria), with and without activation. In vivo, not mutagenic: rats
exposed via inhalation for 13 weeks at doses up to 20 ppm were without
effects on bone marrow (micronucleus assay).

Carcinogenicity : No information.

Reproduction: Acetic anhydride was fetotoxic to rats exposed to the highly
irritating, maternally toxic dose of 100 ppm vapor. No reproductive
effects were seen at 25 ppm.

Repeated Exposure: In a two-week study, respiratory tract irritation was
reported in rats exposed to 25, 100 or 400 ppm acetic anhydride. In a 13
week inhalation study, rats were exposed for 6 hrs./day, 5 days/week to 1,
5 or 20 ppm acetic anhydride vapor. Clinical observation of eye &
respiratory tract irritation and reduced body weights were observed
primarily at 20 ppm. Microscopic examination of tissues revealed minimal
signs of irritation in the respiratory tract in most animals at the 5 ppm
exposure level. At 20 ppm, all animals showed minimal to moderate signs
of respiratory tract irritation. No effects were detected at 1 ppm. In
animals exposed to the same levels (1, 5 and 20 ppm) of acetic anhydride
for 13 weeks and then allowed a 13 week period without exposure,
significant recovery from irritation effects was reported. In summary,
the effects were consistent with those typical of substances which act as
local/site-of-contact irritants.

產品名稱: Acetic anhydride
MSDS 炭碼: 5
材料炭碼: 80005
公垦日期�? 02/02/2006
Ecotoxicity: Acetic anhydride readily hydrolyzes to acetic acid in water
(see Environmental Fate section). The toxic threshold concentrations for
acetic anhydride in various laboratory tests with aquatic organisms were
found to be about half those for acetic acid. This suggests an initial
toxic effect from acetic anhydride so long as not all of the substance has
hydrolyzed to acetic acid (during the first few minutes).

For protozoa the toxic threshold concentration for acetic anhydride is
between 30 and 735 mg/l:

Chilomonas paramaecium, 48-hour Toxic Threshold Concentration = 395
mg/l(cell multiplication inhibition test)

Entosiphon sulcatum, 72-hour Toxic Threshold Concentration

5% Effect Concentration =EC5) = 30 mg/l(cell multiplication inhibition
test)

Uronema parduzci, Toxic Threshold Concentration = 735 mg/l(limited
details; test duration not specified)

The toxic threshold concentration for bacteria (source: domestic
wastewater treatment plant), as determined in the 24-hour fermentation-
tube test, was 2,500 mg/l. The endpoint was inhibition of respiration and
the parameter measured was oxygen consumption. In the cell proliferation
inhibition test (16 hrs.) with Pseudomonas putida a toxic threshold
concentration (3% Effect Concentration = EC3 ) of 1,150 mg/l was found.

In the cell multiplication inhibition test (8 days), the following toxic
threshold concentrations (EC3) were determined:

Microcystis aeruginosa (cyanobacteria): 18 mg/l
Scenedesmus quadricauda (green algae): 3,400 mg/l

In a 5-day study with Chlorella pyrenoidosa (algae) using chlorophyll
reduction as the endpoint, 16.6% to 96.6% reduction was noted compared to
the controls over the concentration range 50 mg/l to 400 mg/l.

Environmental Fate:

Degradation: In natural bodies of water, acetic anhydride hydrolyses
according to a first-order reaction to acetic acid. On the basis of
experimentally determined rate constants, one can calculate half-lives,
t1/2, of 4.4 min. (at 25�?) and 8.1 min. (at 15�?).

This hydrolytic degradation to acetic acid also occurs in the atmosphere.
On the basis of an experimentally determined rate constant, for the
degradation of acetic acid through reaction with photochemically formed
OH-radicals in the atmosphere a half-life of 22 days has been calculated.
However, on account of its high solubility, acetic acid will be rapidly
washed out of the atmosphere.

In the static Zahn-Wellens test of biodegradability, acetic acid is
degraded to more than 95% within 5 days. In the respirometer test (22 -
24 hours in modified MITI test) acetic acid is degraded to 99%.

Bioaccumulation: For acetic anhydride an n-octanol/water partition
coefficient, log Pow, of -0.27 has been calculated, while for acetic acid
a log Pow of -0.17 has been experimentally determined. Neither value
gives any indication of a potential for bioaccumulation.
