Glycolaldehyde dimethyl acetal（CAS# 30934-97-5)

Kupu Whakataki

Ko te Hydroxyacetaldehyde dimethylacetal (2,2-dimethyl-3-hydroxybutyraldehyde) he pūhui waro. E whai ake nei he kupu whakataki mo tona ahuatanga, te whakamahinga, te tikanga whakarite me nga korero haumaru:

Kounga:

1. Ko te Hydroxyacetaldehyde dimethylacetal he wai hinuhinu kore tae ki te kowhai me te kakara kakara motuhake.

2. He ngawari te rewa, ka uru ki roto i te waihano me te chloroform, ka memeha noa ki te wai.

3. No te pūhui aldehyde te pūhui, he mea whakaheke, ka taea te tauhohe ki etahi hāora.

Whakamahia:

1. Ka whakamahia hei takawaenga nui i roto i etahi tauhohenga whakahiato waro, penei mo te whakahiato o te huaora B6 me te benzidine me etahi atu puhui.

2. Ka whakamahia hei kaikawe mo etahi waikano rewharewha, hei kai whakaheke ranei i roto i te whakahiato waro.

Tikanga:

He maha nga huarahi hei whakarite i te hydroxyacetaldehyde dimethylacetal, a ko te tikanga noa ka riro mai i te resorcinol me te acetone tauhohenga. Ko nga hikoinga motuhake e whai ake nei: ko te resorcinone i te tuatahi ka tauhohehia ki te wairewa waipiro waikawa kia hanga glycidyl, ka whakamahanahia ki te acetone i raro i nga tikanga waikawa kia whiwhi ai i te hydroxyacetaldehyde dimethylacetal.

Mōhiohio Haumaru:

1. I te wa e whakamahi ana, e rongoa ana ranei i te puhui, karohia te tango i ona kohu me te pa ki te kiri me nga kanohi.

2. I te wa e whakamahi ana, me aro ki te whakamahi i nga taputapu whakamarumaru whaiaro e tika ana, penei i te mau karapu whakamarumaru matū, karaehe whakamarumaru me nga kopare whakamarumaru.

3. Me whai hoki ki nga whakaritenga mahi haumaru me nga ture whakahaere matū.
