Tsare-tsare da Ajiyewa: A RUFE KWANTA DA KYAU LOKACIN DA AKAYI AMFANI.KAYA A BUSHE WURI.
Dimeryl diisocyanate (DDI) wani nau'in aliphatic ne na musamman (dimer fatty acid diisocyanate) diisocyanate wanda za'a iya amfani dashi tare da mahadi masu dauke da hydrogen mai aiki don shirya ƙananan nauyin kwayoyin halitta ko polymers na musamman.
DDI wani yanki ne mai tsayi mai tsayi tare da babban sarkar dimeric fatty acids tare da kwayoyin carbon guda 36.Wannan tsarin kashin baya yana ba DDI mafi girman sassauci, juriya na ruwa da ƙarancin guba akan sauran isocyanates aliphatic.
DDI ƙaramin ɗanko ruwa ne wanda ke da sauƙin narkewa a mafi yawan kaushi na polar ko nonpolar.
